Description Peter Eriksson 2023-07-27 19:13:04 UTC 
Got a sudden panic & reboot on our test server earlier today running FreeBSD 13.2-RELEASE-p1 while I was running some "make buildworld" on it:

Fatal trap 9: general protection fault while in kernel mode
cpuid = 36; apic id = 30
instruction pointer     = 0x20:0xffffffff80f493c9

processor eflags        = interrupt enabled, resume, IOPL = 0
current process         = 0 (thread taskq)
trap number             = 9

Before that panic I got an MCA check (about an hour before the panic & reboot):

Jul 27 10:22:20 runur00 kernel: MCA: Bank 12, Status 0x8800004000300e0f

and a couple of hours ago I got another:

Wonder if there might be a bad CPU or memory chip somewhere. Hmm...
