5.6 frequent kernel freezes or crashes while running X11

while running X11 on my T60 with ATI video (dmesg below) on 5.6 I get
frequent lock-ups (kernel freezes, reset) or kernel panics.
This happens usually when browsing with seamonkey and browsing several
sites or anyway with a busy desktop. Just a xterm works :)

I did run 5.5 on the same laptop and it was stable, i did not experience
these probelms

In case of a panic I see:

panic: kernel diagnostic asserion "__mp_lock_held(&sched_lock) == 0"
failed: file "../../../../kern/kern_lock.c", 1ine 128

I was able to get a trace and a ps screenshot, which I do not retype,
but attach here:

Traces on cpu0 just shows a kernel lock and trap with the panic call

Trace on cpu1 shows a call from Xinitripi() and Xintrltimer()

The processes screenshot is here: essentially emacs, xterm and browsing.
