Kernel Bug: Total freeze of the system after random time.
Description: From 2.4.0test12 (patch 7), 2.4.0-test13pre2 too, my linux system
freeze EVER after a variable time (one hour or two). There is not a backtrace,
or kernel message dump, it only stayed freezed y I must restart the computer.
It happaned when I went back to a window o task, that it had been inactive for
a minutes (may be cache?).
Sorry about my horrible english, and my poor description, I'm not a programmer
o somethig else, I'm a doctor of medicine and I don't know much about kenel
problems report. I hope I can help you.
Thanks, Ignacio.
