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):
kernel-smp-2.4.22-1.2061.nptl

How reproducible:
Always

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.

Please upgrade to the rawhide kernel.

Comment 2 Dave Jones 2003-11-18 16:44:49 UTC

Is this still a problem with the final FC1 kernel ?

Comment 3 Kurt 2003-11-18 17:17:44 UTC

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 19:15:06 UTC

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).
