I've been infrequently following snapshots with a vbox installation and have been experiencing hangs like this for a year or two now. Everything works great on my actual hardware.
The VM boots fine after resetting, but the subsequent fsck and performing the skipped upgrade steps is mildly annoying. >From the install ramdisk, how would I go about collecting more diagnostic information? Thanks. --david (dmesg below, apologies for line-wrapping) OpenBSD 7.6-beta (GENERIC) #274: Fri Aug 23 19:04:48 MDT 2024 dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC real mem = 1056899072 (1007MB) avail mem = 1001926656 (955MB) random: good seed from bootblocks mpath0 at root scsibus0 at mpath0: 256 targets mainbus0 at root bios0 at mainbus0: SMBIOS rev. 2.5 @ 0xe1000 (10 entries) bios0: vendor innotek GmbH version "VirtualBox" date 12/01/2006 bios0: innotek GmbH VirtualBox acpi0 at bios0: ACPI 4.0 acpi0: sleep states S0 S5 acpi0: tables DSDT FACP APIC SSDT acpi0: wakeup devices acpitimer0 at acpi0: 3579545 Hz, 32 bits acpimadt0 at acpi0 addr 0xfee00000: PC-AT compat cpu0 at mainbus0: apid 0 (boot processor) cpu0: Intel(R) Core(TM) i5-6360U CPU @ 2.00GHz, 1860.00 MHz, 06-4e-03 cpu0: cpuid 1 edx=178bfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CFLUSH,MMX,FXSR,SSE,SSE2,HTT> ecx=56da220b<SSE3,PCLMUL,MWAIT,SSSE3,CX16,PCID,SSE4.1,SSE4.2,MOVBE,POPCNT,AES,XSAVE,AVX,RDRAND> cpu0: cpuid 6 eax=4<ARAT> cpu0: cpuid 7.0 ebx=842529<FSGSBASE,BMI1,AVX2,BMI2,INVPCID,RDSEED,CLFLUSHOPT> edx=30000400<MD_CLEAR,L1DF> cpu0: cpuid 80000001 edx=28100800<NXE,RDTSCP,LONG> ecx=121<LAHF,ABM,3DNOWP> cpu0: cpuid 80000007 edx=100<ITSC> cpu0: MELTDOWN cpu0: 32KB 64b/line 8-way D-cache, 32KB 64b/line 8-way I-cache, 256KB 64b/line 4-way L2 cache, 4MB 64b/line 16-way L3 cache cpu0: smt 0, core 0, package 0 mtrr: CPU supports MTRRs but not enabled by BIOS cpu0: apic clock running at 1000MHz cpu0: mwait min=64, max=64 ioapic0 at mainbus0: apid 1 pa 0xfec00000, version 20, 24 pins, remapped acpiprt0 at acpi0: bus 0 (PCI0) acpipci0 at acpi0 PCI0: 0x00000000 0x00000011 0x00000001 acpibat0 at acpi0: BAT0 model "1" serial 0 type VBOX oem "innotek" acpiac0 at acpi0: AC unit online acpicpu0 at acpi0: C1(@1 halt!) acpivideo0 at acpi0: GFX0 cpu0: using VERW MDS workaround (except on vmm entry) pci0 at mainbus0 bus 0 pchb0 at pci0 dev 0 function 0 "Intel 82441FX" rev 0x02 pcib0 at pci0 dev 1 function 0 "Intel 82371SB ISA" rev 0x00 vga1 at pci0 dev 2 function 0 "InnoTek Graphics Adapter" rev 0x00 wsdisplay0 at vga1 mux 1: console (80x25, vt100 emulation) wsdisplay0: screen 1-5 added (80x25, vt100 emulation) em0 at pci0 dev 3 function 0 "Intel 82540EM" rev 0x02: apic 1 int 19, address 08:00:27:e9:64:ff "InnoTek Guest Service" rev 0x00 at pci0 dev 4 function 0 not configured ohci0 at pci0 dev 6 function 0 "Apple Intrepid USB" rev 0x00: apic 1 int 22, version 1.0 piixpm0 at pci0 dev 7 function 0 "Intel 82371AB Power" rev 0x08: apic 1 int 23 iic0 at piixpm0 em1 at pci0 dev 8 function 0 "Intel 82540EM" rev 0x02: apic 1 int 16, address 08:00:27:1f:8f:14 em2 at pci0 dev 9 function 0 "Intel 82540EM" rev 0x02: apic 1 int 17, address 08:00:27:13:48:5a ehci0 at pci0 dev 11 function 0 "Intel 82801FB USB" rev 0x00: apic 1 int 19 usb0 at ehci0: USB revision 2.0 uhub0 at usb0 configuration 1 interface 0 "Intel EHCI root hub" rev 2.00/1.00 addr 1 ahci0 at pci0 dev 13 function 0 "Intel 82801HBM AHCI" rev 0x02: apic 1 int 21, AHCI 1.1 ahci0: device on port 0 didn't come ready, TFD: 0x171<ERR> ahci0: port 0: 3.0Gb/s scsibus1 at ahci0: 32 targets sd0 at scsibus1 targ 0 lun 0: <ATA, VBOX HARDDISK, 1.0> t10.ATA_VBOX_HARDDISK_VBa5540626-6a15461b_ sd0: 20480MB, 512 bytes/sector, 41943040 sectors isa0 at pcib0 isadma0 at isa0 pckbc0 at isa0 port 0x60/5 irq 1 irq 12 pckbd0 at pckbc0 (kbd slot) wskbd0 at pckbd0: console keyboard, using wsdisplay0 pms0 at pckbc0 (aux slot) wsmouse0 at pms0 mux 0 pcppi0 at isa0 port 0x61 spkr0 at pcppi0 usb1 at ohci0: USB revision 1.0 uhub1 at usb1 configuration 1 interface 0 "Apple OHCI root hub" rev 1.00/1.00 addr 1 vscsi0 at root scsibus2 at vscsi0: 256 targets softraid0 at root scsibus3 at softraid0: 256 targets root on sd0a (ddf460662c748e5c.a) swap on sd0b dump on sd0b WARNING: /mnt was not properly unmounted
