I think it was syscall: https://marc.info/?l=openbsd-bugs&m=145135041623692&w=2 > Both of those instructions can indeed generate #UD, but apparently only > if you either aren't in 64 bit mode (not the case) or if EFER gets trashed > (likely not the case either). So, I'm stumped. On amd64, the kernel generates a SIGILL on: an undefined/illegal instruction (well, duh ;-) and on an FP coprocessor fetch fault. Then there's the routine sendsig() in amd64/machdep.c that copies out FPU state, signal context, etc. to the user process as I can understand so far. When the copyout() fails, the kernel calls sigexit(SIGILL), which terminates the process. So what I suspect to happen is that: - userland does a syscall - something goes wrong in the kernel, causing it to call sigexit(SIGILL), terminating the process - and the offending instruction you see in the core dump is the 'syscall' instruction. > I don't have any other advice at the moment, but am replying here to > keep the thread up to date with what I recall being the most up to date > info. > > -ml > > > > > I've done installs of 5.7, 5.8 and -current multiple times on all three > > of these machines.
