https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D241059 Bug ID: 241059 Summary: random kernel panics Product: Base System Version: 12.1-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: chris@cretaforce.gr The last days I enable dumpdev to get crashdump for crashes that randomly happen to my servers. I can provide shell access to a developer to check the core.=20 ------ 12.1-BETA1 panic: general protection fault Fatal trap 9: general protection fault while in kernel mode cpuid =3D 1; apic id =3D 01 instruction pointer =3D 0x20:0xffffffff81098b76 stack pointer =3D 0x28:0xfffffe009c39e7e0 frame pointer =3D 0x28:0xfffffe009c39e8c0 code segment =3D base 0x0, limit 0xfffff, type 0x1b =3D DPL 0, pres 1, long 1, def32 0, gran 1 processor eflags =3D interrupt enabled, resume, IOPL =3D 0 current process =3D 37432 (bash) trap number =3D 9 panic: general protection fault cpuid =3D 1 time =3D 1570197605 KDB: stack backtrace: #0 0xffffffff80c1bd47 at kdb_backtrace+0x67 #1 0xffffffff80bcf07d at vpanic+0x19d #2 0xffffffff80bceed3 at panic+0x43 #3 0xffffffff810a6d2c at trap_fatal+0x39c #4 0xffffffff810a613c at trap+0x6c #5 0xffffffff8107fdcc at calltrap+0x8 #6 0xffffffff80f0fadc at vmspace_exit+0x9c #7 0xffffffff80b88fb9 at exit1+0x5d9 #8 0xffffffff80b889dd at sys_sys_exit+0xd #9 0xffffffff810a78e4 at amd64_syscall+0x364 #10 0xffffffff810806f0 at fast_syscall_common+0x101 Uptime: 8d15h44m0s Dumping 2383 out of 32589 MB:..1%..11%..21%..31%..41%..51%..61%..71%..81%..= 91% __curthread () at /usr/src/sys/amd64/include/pcpu.h:234 234 /usr/src/sys/amd64/include/pcpu.h: No such file or directory.
