User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6a) Gecko/20030926

Description of problem:
I get a random system lockup after about a hours use when using the SMP kernel
(kernel-smp-2.4.22-1.2061.nptl) and not the non-SMP kernel
(kernel-2.4.22-1.2061.nptl) on my single (but hyperthreaded) CPU computer.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. boot computer and select SMP kernel.
2. use the computer a about an hour.

Actual Results:  the computer gets locked up.

Expected Results:  the computer works normally.

Comment 1 Bill Nottingham 2003-10-08 18:24:59 EDT
Please upgrade to the rawhide kernel.
Comment 2 Dave Jones 2003-11-18 11:44:49 EST
Is this still a problem with the final FC1 kernel ?
Comment 3 Kurt 2003-11-18 12:17:44 EST
The FC1 kernel fixed the problem (vmlinuz-2.4.22-1.2105.nptlsmp).
However, system shutdowns occansionally hang just after disk halting,
with or without "apm=power-off" option in grub.conf. I guess a new bug
entry is in order for this.
Comment 4 Dave Jones 2003-11-20 14:15:06 EST
Yeah, please open up a new one. (Better yet, do a search first, this
sounds familiar, there may already be an open bug for this).
