Not super fast but I don't think it signals a bug. When I upgraded my VPS to 7.2 it took more than 10 minutes (no kidding) to load the kernel and reach the "entry point at..." step after typing my passphrase, then everything was normal. I only rebooted the OS to either (7.2) bsd.rd or (7.2) bsd, I didn't try to turn the machine off or boot another kernel after that. It was the first time I observed such a thing with this instance in 6 years. Dmesg below just in case, as it is a virtual machine there could be many reasons to explain this behavior.

Re: obsd install initial boot process slowed down
Hi Sylvain, [Cc: tech@ removed. Do not cross post.] While Nick and Stuart has assisted you with the question per se, I'd like to point out a totally non-technical issue that at least caused me a little confusion from the beginning: On Wed, Jan 04, 2023 at 07:13:23AM +0100, Sylvain Saboua wrote: > ... > The initial boot process, right after I type the security > key in, which displays cyphers aligning in between rotating > semicolumns (I hope this is clear), is slow, on this install. I believe the word you're looking for is not "cyphers", but rather "digits". Assuming you're french, "chiffres" would also be a proper translation for "cyphers" (or "ciphers"), but that refers to cryptographic methods, and not the digits [0-9]. Cheers, Alexander

None of those issues are of the form “a hundred bad bytes will permanently and irrevocably destroy all data on your entire disk”. Unless I am mistaken, crypto header corruption is.

OpenBSD supports only class-compliant MIDI devices. Not all old devices are class-compliant because in the 2000's, Windows used to have a bug that hardware designers tried to workaround. Certain devices from the 2000's have a switch (or configuration parameter) to switch between vendor-specific and class-compliant modes. Try to dig in the manual. If you can't switch the device to class-compliant mode, get a USB-MIDI interface, they are cheap nowadays and just work. > $ cat /etc/rc.conf.local > pkg_scripts=avahi_daemon messagebus gdm cups_browsed > sndiod_flags=-z 128 -f rsnd/1 > > $ cat /etc/sysctl.conf > kern.audio.record=1 > > sndiod flags are for reduced latency and for audio to work properly on my > Huawei MateStation. seems correct

I know that it works with various Linux distributions, which to my understanding also work with class compliant devices as a point of reference. However, the Roland A-800 Pro also has an "ACT" mode which requires a Windows driver if used. I have never used it in "ACT" mode and never needed a special driver.

Issues booting alpine linux > 3.5 on vmm - openbsd7.2
Hi OpenBSD friends,
Just a report, not sure if it's helpful, but @voutilad requested [1] I
send the details to the mailing list.
I have seen a few reports online[1][2], about some users not being able to
boot newer alpine linux versions (and other linux OS' in my
experience). Specifically I've seen the last version that boots is
3.5.3.
My system is openbsd 7.2 on my hardware Lenovo ThinkPad E14 Gen 4
laptop.
The issue, when the alpine linux VM boots, it kernel panics.

I'm not on -current and not familiar with openbsd enough to switch (or
have the time to look at it now).
Any suggestions would be good.

openbsd 7.2 suspend / sleep issues on Lenovo ThinkPad E14 Gen 4
Greetings All :) Generally openbsd7.2 works well on Lenovo ThinkPad E14 Gen 4. Their is two main things that aren't working. The camera. Which is less important, because I can plug an external usb web cam. The camera is detected, but doesn't work. I think it was recording weirdly or in some crippled fashion. The main issue is trying to put the laptop to sleep / suspend or hibernate. In the BIOS if it's set to "s3 state", when I do =apm -S= or =apm -z= it does put the system to sleep but when I resume it powers the machine on from scratch. If in the BIOS I have power sleep state set to "windows or linux" (the default), then both =apm -z= or =apm -S= simply, do nothing (except print to the screen that it will go to sleep). I guess it is new hardware. Not a great idea to have the latest hardware I guess when you want to run openbsd I guess. Sadly, it's what workplaces tend to buy (and they not flexible). Lastly when I try hibernate the system, it invokes hibernation and it appears to resume. However it doesn't restore it properly. It seems to get stuck right at the end of the hibernation and when switching to X, one just sees a cursor flash. Here is my system dmesg[1](dups removed). Here is a dmesg from a failed hibernation resume[2](dups removed). Let me know if anyone wants more info or has any suggestions for me to try to get it working. These lines look concerning... drm:pid91368:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 [1]: R* Fault errors on pipe A: 0x0080 drm:pid91368:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid28195:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid86263:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid28195:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid28195:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid28195:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid28195:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid28195:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid28195:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid28195:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid28195:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid28195:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid28195:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid28195:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid28195:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid28195:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid28195:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid28195:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid28195:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid28195:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid28195:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid28195:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid28195:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid28195:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid28195:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid28195:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid28195:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid28195:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid28195:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid28195:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid28195:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid28195:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid28195:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid28195:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid28195:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid28195:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid28195:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x0080 drm:pid28195:gen8_de_irq_handler *ERROR* [drm] *ERROR* Fault errors on pipe A: 0x00
Re: Change (spoof) MAC address
Hi everyone, Work week is over and I have time to play with real hardware. Just wanted to let you know that this configuration did work: # cat /etc/hostname.re0 inet autoconf lladdr 00:11:22:33:44:55 # ifconfig re0 re0: flags=808843 mtu 1500 lladdr 00:11:22:33:44:55 index 1 priority 0 llprio 3 groups: egress media: Ethernet autoselect (100baseTX full-duplex) status: active inet 192.168.0.208 netmask 0x broadcast 192.168.255.255 But it did not work within VirtualBox. Possibly a bug? Best regards

The key issue here is the invalid opcode error coming from the
instruction starting with 66 0f ae, which is a TPAUSE
instruction. Hence the RIP pointing to "delay_halt_tpause" in the Linux
kernel.
I don't think I have any newer Intel hardware that supports the "User
Wait" instructions (aka WAITPKG). My Intel research says it premiered in
Tremont, Alder Lake, Sapphire Rapids so I can't test locally, but the
docs from Intel (SDM Vol. 2B 4-719) say:
Prior to executing the TPAUSE instruction, an operating system may
specify the maximum delay it allows the processor to suspend its
operation. It can do so by writing TSC-quanta value to the
following 32-bit MSR (IA32_UMWAIT_CONTROL at MSR index E1H)...
We probably should be masking the CPUID value for TPAUSE in the values
vmm(4) communicates via vmm_handle_cpuid.

About the camera, here is some more useful info on how it doesn't work: I've enabled the webcam in the bios now and here is a more useful report with a dmesg[1] with integrated cam enabled.
