https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D255393 Bug ID: 255393 Summary: panic: vm_fault_lookup: fault on nofault wntry, addr: 0xccf4000 Product: Base System Version: 13.0-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: dclarke@blastwave.org Created attachment 224423 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D224423&action= =3Dedit grayscale image of the console This is a difficult crash to report given that I can not install gdb and all attempts to install a few packages will result in a crash. Thus far the machine has crashed at least four times and I will report what I see in crash number 3. While I was trying to get info about crash #3 the machine crashed again. Here is what I saw on the console :=20 panic: vm_fault_lookup: fault on nofault entry, addr: 0xccf4000 cpuid =3D 0 time =3D 1619357501 KDB: stack backtrace: #0 0x10491df at kdb_backtrace+0x4f #1 0x100276a at vpanic+0x11a #2 0x1002644 at panic+0x14 #3 0x12a1fc3 at vm_fault+0x1753 #4 0x12a07a7 at vm_fault_trap+0x87 #5 0x13e99f6 at trap_pfault+0x146 #6 0x13e8fc1 at trap+0x381 #7 0xffc0319f at __stop_set_sysinit_set+0xe4400673 #8 0x28 at ll+0x7 Uptime: 22m38s Physical memory: 933 MB Dumping 142 MB: 127 111 95 79 63 47 31 15 Dump complete Of course I can not provide much more as there is no gdb installed however I can try to tarball the core dumps. What I do not know is if there is security data inside those files such as passwords etc. I will attach am image that I took of the console with my cellphone. I converted it to grayscale png to reduce size. Next big trick will be to attach the actual vmcore files etc. However the machine usually crashes when asked to do much of anything.=20 --=20 Dennis Clarke RISC-V/SPARC/PPC/ARM/CISC UNIX and Linux spoken GreyBeard and suspenders optional --=20 You are receiving this mail because: You are the assignee for the bug.=
