FreeBSD Crashes Intermittently !!

[lokadamus at gmx.de]

Hi,

I think about the error lines:
Hardware event. This is not a software error.
CPU 23 BANK 5
MISC 0 ADDR 805613c60
MCG status:MCIP
STATUS be00000000800400 MCGSTATUS 4
....
Hardware event. This is not a software error.
CPU 22 BANK 5

https://en.wikipedia.org/wiki/Machine-check_exception

Looks like a hardware problem from the second cpu.
Thinks, what can be done:
- Is it possible to read cpu heat infos from bios?
- Disable HTT and look, if the error comes again
- Remove the second cpu and look, if ...
- Install microcode updates and hope, it will fix it

Intel offers for many CPUs an microcode update.

Can you test a cpu in another system?
