With kernel preemption, all work perfectly.
Without kernel preemption, they are many bugs:
- under medium/high load, gcc crash randomly
- mozilla have trouble to render (each refresh show a new page)
- xmms segfault under medium/high load (sound crackle and segfault)
- mplayer too

I think you switched with and without.

And on time, X freeze.

Kernel preemption isn't usuable under linuxppc ?

The situation is going better but it is still not usable.

Can you try isolating a given activity or driver that cause the
stability problem ? It should work, really...

For example, try running without the cpufreq driver ... or without the
sound driver, etc...


Problem exist without cpufreq.
I'm try without running X, only in console: nothing append.

I use XFree 4.3 from debian testing, and with radeon driver, without dri (for
make pmdisk work)

Test in progress...
