Hola, For roughly a week I have been able to reliably produce panics on amd64 (virtual machine and physical machine) using disk IO heavy applications (gitea, syncthing).
Unfortunately on the physical machine - the one I can reliably panic within < 1 minute - I don't have a serial console, so here are links to photos: https://goo.gl/photos/Z8g225UXXpCXQpGcA mirror/google averse: https://deftly.net/panic-2017-07-06/ Also with machdep.forceukbd=1, once I ran `mach ddbcpu 0`, every subsequent key press puked out an "splassert" line, I attempted to run a "trace" again, but things seemed to be completely locked up after that. Cheers, Aaron OpenBSD 6.1-current (GENERIC.MP) #89: Thu Jul 6 01:02:18 MDT 2017 [email protected]:/usr/src/sys/arch/amd64/compile/GENERIC.MP real mem = 4231942144 (4035MB) avail mem = 4097892352 (3908MB) mpath0 at root scsibus0 at mpath0: 256 targets mainbus0 at root bios0 at mainbus0: SMBIOS rev. 2.7 @ 0xe0840 (49 entries) bios0: vendor Phoenix Technologies Ltd. version "CDV_T30 X64" date 09/17/2012 bios0: Intel Corporation Milstead Platform acpi0 at bios0: rev 2 acpi0: sleep states S0 S1 S3 S4 S5 acpi0: tables DSDT FACP SLIC SSDT HPET APIC MCFG SSDT UEFI UEFI POAT UEFI acpi0: wakeup devices P0P1(S4) USB0(S4) USB1(S4) USB2(S4) USB3(S4) EHC1(S4) USB4(S4) USB5(S4) USB6(S4) EHC2(S4) PXSX(S4) RP01(S4) PXSX(S4) RP02(S4) PXSX(S4) RP03(S4) [...] acpitimer0 at acpi0: 3579545 Hz, 24 bits acpihpet0 at acpi0: 14318179 Hz acpimadt0 at acpi0 addr 0xfee00000: PC-AT compat cpu0 at mainbus0: apid 0 (boot processor) cpu0: Intel(R) Atom(TM) CPU D2550 @ 1.86GHz, 1862.32 MHz cpu0: FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CFLUSH,DS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE,SSE3,DTES64,MWAIT,DS-CPL,TM2,SSSE3,CX16,xTPR,PDCM,MOVBE,NXE,LONG,LAHF,PERF,ITSC,SENSOR,ARAT cpu0: 512KB 64b/line 8-way L2 cache cpu0: TSC frequency 1862322420 Hz cpu0: smt 0, core 0, package 0 mtrr: Pentium Pro MTRR support, 8 var ranges, 88 fixed ranges cpu0: apic clock running at 133MHz cpu0: mwait min=64, max=64, C-substates=0.1, IBE cpu1 at mainbus0: apid 1 (application processor) cpu1: Intel(R) Atom(TM) CPU D2550 @ 1.86GHz, 1862.01 MHz cpu1: FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CFLUSH,DS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE,SSE3,DTES64,MWAIT,DS-CPL,TM2,SSSE3,CX16,xTPR,PDCM,MOVBE,NXE,LONG,LAHF,PERF,ITSC,SENSOR,ARAT cpu1: 512KB 64b/line 8-way L2 cache cpu1: smt 1, core 0, package 0 cpu2 at mainbus0: apid 2 (application processor) cpu2: Intel(R) Atom(TM) CPU D2550 @ 1.86GHz, 1862.01 MHz cpu2: FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CFLUSH,DS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE,SSE3,DTES64,MWAIT,DS-CPL,TM2,SSSE3,CX16,xTPR,PDCM,MOVBE,NXE,LONG,LAHF,PERF,ITSC,SENSOR,ARAT cpu2: 512KB 64b/line 8-way L2 cache cpu2: smt 0, core 1, package 0 cpu3 at mainbus0: apid 3 (application processor) cpu3: Intel(R) Atom(TM) CPU D2550 @ 1.86GHz, 1862.01 MHz cpu3: FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CFLUSH,DS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE,SSE3,DTES64,MWAIT,DS-CPL,TM2,SSSE3,CX16,xTPR,PDCM,MOVBE,NXE,LONG,LAHF,PERF,ITSC,SENSOR,ARAT cpu3: 512KB 64b/line 8-way L2 cache cpu3: smt 1, core 1, package 0 ioapic0 at mainbus0: apid 1 pa 0xfec00000, version 20, 24 pins acpimcfg0 at acpi0 addr 0xe0000000, bus 0-255 acpiprt0 at acpi0: bus 0 (PCI0) acpiprt1 at acpi0: bus 7 (P0P1) acpiprt2 at acpi0: bus 1 (RP01) acpiprt3 at acpi0: bus 2 (RP02) acpiprt4 at acpi0: bus 3 (RP03) acpiprt5 at acpi0: bus 4 (RP04) acpiprt6 at acpi0: bus 5 (RP05) acpicpu0 at acpi0: C1(@1 halt!) acpicpu1 at acpi0: C1(@1 halt!) acpicpu2 at acpi0: C1(@1 halt!) acpicpu3 at acpi0: C1(@1 halt!)
