Tonight I had a kernel panic (full hang) with the following on the console: CPU 0: Machine Check Exception: 0000000000000004 Bank 4: b200000000070f0f Kernel panic - not syncing: CPU context corrupt I tried to decode this: # ./parsemce -e 0000000000000004 -b 4 -s b200000000070f0f -a 0 Status: (4) Machine Check in progress.

The kernel is 2.6.16-gentoo-r9 and the CPU is an A64 "Venice" 3500+ I can post further hw/sw environment information if req'd. Thanks! Regards, Sab
