I got kernel Panic with MCE 7 on my Athlon XP 2600 (kernel 2.4.18).
I think it's a hardware problem, but not sure. The freeze arise
from time to time, especially under heavy load
(big cpu-mem transfert, kernel compiling, by example).

What can be the problem ? Is this the better place to ask ?
Thanks in advance. Details here under.

On a 2.4.18 kernel (proc: Athlon XP 2600), I sometimes get this MCE:
"kernel: CPU 0: Marchine Check Exception: 0000000000000007
  kernel: Bank 3: b400000000000833 at 3400000000000833
  kernel: Kernel panic: Unable to continue"

Using parsecme I get this
./parsemce -b 3 -s b400000000000833 -a 3400000000000833 -e 7

Status: (7) Machine Check in progress.
Error IP valid
Restart IP valid.
parsebank(3): b400000000000833 @ 3400000000000833
         External tag parity error
         Address in addr register valid
         Error enabled in control register
         Error not corrected.
         Bus and interconnect error
         Participation: Local processor originated request
         Timeout: Request did not timeout
         Request: Generic error
         Transaction type : Instruction
         Memory/IO : Other

Dont know exactly what it means. Hardware problem ?
(bad RAM module, bad chipset, bad cpu?)
