What cheat codes are you using? This is just a wild guess, but if ACPI isn't working correctly your machine might be overheating.

BTW, it's ' cat /proc/cpuinfo ', not etc.

What kind of specs does your system have, CPU, cdrom, video card, is it a laptop, etc.

The error really got me confused. Could the error be attributed to error in hardware?
Thanks.
