Machine Check Exception
Today, for the first time, I got this message during boot (just after
some messages from ohcihcd):
CPU 0: Machine Check Exception: 4
Bank 4: b200000000070f0f
This is not a software problem!
Run through mcelog --ascii to decode and contact your hardware vendor
Kernel panic - not syncing: Machine check
Well, mcelog --ascii does not help much, to say the truth:
HARDWARE ERROR. This is *NOT* a software problem!
Please contact your hardware vendor
CPU 0 4 northbridge TSC a38a02f0b
Northbridge Watchdog error
bit57 = processor context corrupt
bit61 = error uncorrected
bus error 'generic participation, request timed out
generic error mem transaction
generic access, level generic'
STATUS b200000000070f0f MCGSTATUS 4
The processor is an Athlon 64 3000+, on a Asus K8U-X motherboard.
The error first appeared just after I plugged a USB webcam in my system.
However, both times resetting the system made it boot correctly.
So, how should that messages be interpreted?
Experience is the worst teacher. It always gives the test first and
the instruction afterward.
