I have Slackware 12 running on Dual Xeon E5420, Intel 5000VSA and at about 3 times a week I experience kernel panic with machine check exception error code 00..04. I'd like to be sure if this is or not a hardware error.
I want to debug further this MCE error but I couldn't find any valid source of mcelog. ftp.x86-64.org is not accesible and I tried with some .src.rpms for fedora, mandriva - I get dependencies errors that I coulnd't fix of this Slackware machine. My kernel is 2.4.26.2-smp.

I have contacted Intel - they didn't bother to answer my email. Instead they send me a link for reviewing their customer support...

Any ideas ?
Thanks.

Sounds like either a bad processor or RAM.

To check the RAM run memtest86+ on one stick at a time.

Posting your error message might help.

I have reviewed my post: my kernel is 2.6.24.2-smp not 2.4.26....

So here's the panic message:

CPU7: Machine Check Exception: 0000000000000004
CPU5: Machine Check Exception: 0000000000000005
CPU6: Machine Check Exception: 0000000000000004
CPU4: Machine Check Exception: 0000000000000005

Bank 5: b2000001080200e0f <0> Bank 5: b200000044100eof

Frequently this message appears on CPU 5-7(second CPU ), but I have seen also on 1-4.

I guess I should remove the second CPU to see if this thing continues to happen.

Thanks for your answer.
