Kernel panic in 2.4.20-rc2

[Thomas Speck]

Hi,
from time to time (frequency a couple of weeks) I get the following: 

Jan  4 15:32:19 ThS-home kernel: CPU 0: Machine Check 
Exception: 0000000000000004
Jan  4 15:32:19 ThS-home kernel: Bank 1: f200000000000115
Jan  4 15:32:19 ThS-home kernel: Kernel panic: CPU context corrupt

Is that a hardware problem ?
