Hi there,

I also have lockups, but just when running latest fedora's official
Firefox package (plus ADP and flashblock) and not under heavy load. I
am sure that is related to firefox because I have been using Chrome
for some days and no lockup at all.

Yep. I see nothing in system logs. I will give Breakpad
(
http://kb.mozillazine.org/Breakpad) a try disabling extensions as
well to see if I can figure out what the hell is going on there. Any
progress will be posted to the list.

As said above, I experience this only when running Firefox therefore I
think this issue is closely related to this web browser. Anyway, I run
Fedora 12 on an Intel Inspiron 13z with up to date bios.
I had the same problem some years ago with one computer. After I
changed
the power supply, everything was fine. Maybe this can help you...
I don't think this is due to power supply, but thanks for the tip.
