** Description changed: Kernel panic is occured when I copy big files (over 1GB each) and browsing with firefox4 at the same time. System, source and destination HDD are encrypted with Luks AES-XTS. I encountered this panic a number of times in the same situation. But I have NOT encountered this panic when I don't use GUI. (ex: ssh to this machine and copy big files on gnu screen and detach a session.) Error messages are below. It may contain some mistake because I input it manually. ------------------------------- here --------------------------------- [Hardware Error]: CPU 2: Machine Check Exception: 4 bank 0: b600400094000135 [Hardware Error]: TSC 21642801c6556a ADDR 10001fd00 [Hardware Error]: PROCESSOR 2:100fa0 TIME 1309032766 SOCKET 0 APIC 4 [Hardware Error]: MC0_STATUS[-|UE|-|PCC|AddrV|CECC]: 0xb600400094000135 [Hardware Error]: Data Cache Error: Data/Tag DRD error.
