Hi there,
I have an F12 installation that experiences intermittent lockups, usually at times of heavy usage.
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.
The system just locks up solid, keyboard and mouse are non responsive. Graphical screen remains the same as it was when it locked up. Nothing is recorded in the system logs, and I also have logging to a remote machine and nothing is sent to there either. If you attempt to telnet in, you get the first telnet message with the kernel name but no login prompt and it times out. Only a hard reset and reboot gets it back.
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.
I've extensively tested the hard disks and memory. Processor temp is well controlled by a big fan.
This is on an ASUS M4A77D motherboard (AMD 770) with an AMD 9850 processor. I've tried pci=nomsi and it does not seem to change things.
Twice, running yum caused the lockup, but any intensive progam can. It reencodes video early in the morning and has locked up three times then.
Any suggestions would be appreciated.
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.
Regards,
David
