It's sort of unknown here about how "fine" the machine check code works, but I
have seen reports of errors getting logged.  It is sometimes possible for
software to provoke these errors, but that is unusual.  Correctable errors
should be fairly benign.  If you are getting uncorrectable errors, that will
probably cause the machine to reboot.  In either case it is likely to be a
hardware issue of some sort.

I've gotten one correctable error on my machine in the last week:

Jul 22 17:17:17 speedy kernel: MCA: Bank 1, Status 0x90200000000b0151
Jul 22 17:17:17 speedy kernel: MCA: Global Cap 0x0000000000000117, Status
0x0000
000000000000
Jul 22 17:17:17 speedy kernel: MCA: Vendor "AuthenticAMD", ID 0x800f11, APIC ID
14
Jul 22 17:17:17 speedy kernel: MCA: CPU 14 COR ICACHE L1 IRD error

This looks like a correctable level 1 instruction cache read error.  It doesn't
seem to have had any side effects.


What error are you getting?
