mce Hardware Error Machine check events logged -


Hello,

I have acer apspire v3-772G with Slackware 14.1 on it. Today I found this in my dmesg and /var/log/messages

Code:
Jun 26 14:24:51 darkstar kernel: [  300.359668] mce: [Hardware Error]: Machine check events logged
I checked /var/log/messages and found this error start on Jun 18 after upgrade to kernel 3.15.1. This log message appear every time 5 minutes after boot. I execute mcelog and here is the output:

Code:
HARDWARE ERROR. This is *NOT* a software problem!
Please contact your hardware vendor
MCE 0
CPU 0 BANK 8 
MISC 38a0000086 ADDR ffb06d80 
TIME 1403785936 Thu Jun 26 15:32:16 2014
MCG status:
MCi status:
Uncorrected error
MCi_MISC register valid
MCi_ADDR register valid
Processor context corrupt
MCA: corrected filtering (some unreported errors in same region)
Generic CACHE Level-2 Generic Error
STATUS ae0000000040110a MCGSTATUS 0
MCGCAP c09 APICID 0 SOCKETID 0 
CPUID Vendor Intel Family 6 Model 60
Can someone explain me what's failing (and what is the exact problem)? I can not find other clues for hardware problems.

means an error was detected in the CPU L2 cache. This means either the cache has bad bits or the BIOS has not set up the CPU correctly. Is this the original CPU for the laptop?

Yes it is the original CPU. I'm using microcode (release date 2014-05-23) but the errors are before its installation.
Code:

Just checked for new bios version and there is one (release date 2014/04/28) so I will try to upgrade it (but my microcode is newer).

Do you know why it's reported only one time after each boot. MCE check for errors every 5 minutes (as I know) but the error is reported only once and it's 5 minutes after boot (on the first/second check), no such errors before next boot.
Do you know a way to reproduce the problem any time (it will be good if laptop freez/crash) so I can make a demo to the service guy.

Thank you.

iirc, memtest86 checks the cache. Why not run it and see?
