8-STABLE/amd64 semi-regular crash with "kernel trap 12 with interrupts disabled" in "process 12 (swi4: clock)"

[Lev Serebryakov]

Hello, Freebsd-stable.


  One of my servers crashes about once a week, with always same
diagnostics: "kernel trap 12 with interrupts disabled" and in same
process: "swi4: clock"

  It doesn't look as memory failure, as memtest86+ can not find any
errors in 8 passes.

  Also, after this crash server refuse to auto-reboot, last message on
console is "cpu_reset: Stopping other CPUs", and it hangs.

  Kernel config, booting dmesg & results of "savecore" are attached
(bzipped).
