[Bug 224496] mpr and mps drivers seems to have issues with large seagate drives
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=224496 --- Comment #24 from Matthias Pfaller --- (In reply to Bane Ivosev from comment #23) We just gave it another try. We hopped that the problem might have been caused by a defective disk when we tried last. The problem was triggered again during the next night's backup :-( This is forcing us to keep running 11.1 on our backup machines.

[Bug 234733] Setting CPU frequency with sysctl dev.cpu.0.fr slows a Ryzen 2700X down
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=234733 --- Comment #4 from sig...@gmail.com --- Created attachment 210970 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=210970&action=edit acpidump -dt (In reply to Conrad Meyer from comment #3) Alright I tested a bunch of things based on that. It doesn't seem to be related to CPB in this case. The 0x0200 bit never gets set (it always shows "MSR 0xc0010015: 0x 0x0911"). I tried to toggle it on and off again anyway in case it would reset something but it doesn't seem like it does. The CPU just seems to get stuck at the lowest frequency it has been set to. I tested by timing this: dd if=/dev/zero bs=32k count=2 | cpuset -l 0 time sha1 And by setting the frequency to 3200 (maximum), 2800 and 1550: 3200: 1.34 real 1.15 user 0.17 sys 2800: 1.78 real 1.47 user 0.30 sys 1550: 3.18 real 2.78 user 0.39 sys After lowering the frequency to a given value, there's no way to get the performance back (but it lets you set the frequency higher with sysctl without any apparent errors). With debug.hwpstate_verbose set, there's that during boot: hwpstate0: going to fetch info from acpi_perf hwpstate0: on cpu0 And a bunch of messages like that when setting the frequency with sysctl: hwpstate0: setting P1-state on cpu0 hwpstate0: setting P1-state on cpu1 hwpstate0: setting P1-state on cpu2 hwpstate0: setting P1-state on cpu3 hwpstate0: setting P1-state on cpu4 hwpstate0: setting P1-state on cpu5 hwpstate0: setting P1-state on cpu6 hwpstate0: setting P1-state on cpu7 hwpstate0: setting P1-state on cpu8 hwpstate0: setting P1-state on cpu9 hwpstate0: setting P1-state on cpu10 hwpstate0: setting P1-state on cpu11 hwpstate0: setting P1-state on cpu12 hwpstate0: setting P1-state on cpu13 hwpstate0: setting P1-state on cpu14 hwpstate0: setting P1-state on cpu15 hwpstate0: setting P2-state on cpu0 hwpstate0: setting P2-state on cpu1 hwpstate0: setting P2-state on cpu2 hwpstate0: setting P2-state on cpu3 hwpstate0: setting P2-state on cpu4 hwpstate0: setting P2-state on cpu5 hwpstate0: setting P2-state on cpu6 hwpstate0: setting P2-state on cpu7 hwpstate0: setting P2-state on cpu8 hwpstate0: setting P2-state on cpu9 hwpstate0: setting P2-state on cpu10 hwpstate0: setting P2-state on cpu11 hwpstate0: setting P2-state on cpu12 hwpstate0: setting P2-state on cpu13 hwpstate0: setting P2-state on cpu14 hwpstate0: setting P2-state on cpu15 Never anything other than P1 and P2. I tested after a reboot and an update to recent 12-STABLE r356965 and the results were all pretty much the same. That's a B450 Pro4 still with BIOS version P3.20. Using non-UEFI boot. And I reset it to default settings before the last test. At the time I first reported this it had the latest BIOS version but not anymore. So maybe a BIOS update would fix it. I'm gonna wait updating it in case more testing could be helpful. Thanks for looking into it! No other problems apart from that on this computer. And yeah after that I figured that you don't really need to run powerd on these CPUs since they'll throttle themselves automatically anyway and they seem to be doing a good job of it. But if someone does run powerd (or mess with the frequency directly) the permanent and silent slowdown can be a pretty bad surprise. -- You are receiving this mail because: You are the assignee for the bug. ___ freebsd-bugs@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"

[Bug 243531] Unstable ena and nvme on AWS
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=243531 Bug ID: 243531 Summary: Unstable ena and nvme on AWS Product: Base System Version: 12.1-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: b...@freebsd.org Reporter: l...@ofwilsoncreek.com We just recently upgraded our systems on AWS to 12.1, and we're seeing errors with nvme0 and ena0. Typically, these errors manifest together. My sample size is 34 instances, all t3.medium or r4.large. I have others that are t2.small, and those are fine being that they don't use ena or nvme drivers. Of the 34, there's a group of 15 that are almost idle, and never throw these errors. Of the remaining that have load, only 5 ran without errors and 14 of them threw these errors scattered about various times in the last 4.5 days. 3 machines have crashed during this period, so the errors seem to often be nonfatal, but not always. So based on that it seems load related, and does not seem isolated to an occasional hardware problem.

I'm developing a frame buffer driver for hardware using 3 bytes per pixel but the hardware requires the stride to be a multiple of 256 bytes. Because the stride is not a multiple of 3 bytes, the way vt_fb_blank() is coded, it writes past the end of each stride and, on the last line, writes past the end of the frame buffer. This is caught by a KASSERT in vt_fb_mem_wr1(). I think the loops in vt_fb_blank() could just stop at the end of the line (fb_width) instead of clearing memory all the way to the end of a stride. The other way would be to limit the loops with fb_stride - 1, fb_stride - 2, fb_stride - 3 for the cases of 2,3,4 bytes per pixel. -- You are receiving this mail because: You are the assignee for the bug. ___ freebsd-bugs@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"

I'd like to give it a try, but I cannot get any -CURRENT kernel booting on my machine. Both cross-compiled kernels as well as natively-built ones seem to hit the same problem, so it's likely not a GCC9 issue. I'll attach a dmesg.boot file from a natively-built 12-STABLE system to give people a clue on what hardware the system has. The newest kernel that I tested is a cross-built r356986. I re-read AF3e's chapter on crash dumps, trying to provide something useful, but I guess that the crash happens too early and the system cannot dump anything, yet.
