Random freezes - Fedora 16 x86_64, ASRock Z68 Pro3 Gen3

[calris]

Hi All,

I have a brand new ASRo Pro3 Gen3 with a 3.3GHz i5 2500 and 8GB RAM

I'm running Fedora 16 x86-64 with all latest patches (kernel version is 3.1.9-1.fc16.x86_64)

Im experiencing random (anywhere from <1 hour to >12 hours) lockups with a very distinct sympton - a psychedelic flashing sreen (solid colout over entire screen which cycles through various shades of 'bright' colours). When it happens, the machine is totally locked (cannot ping).

I've checked /var/log/messages (attached as messages.log) and Xorg.0.log (attached) but there are not kernel panics or anything suspicious apart from a 'Failed to enable MSI-X' message

Any idea how I can track this down?

I'm not afraid to hack and re-compile the kernel...

Edit: Freezes were happening before updates and also using LXDE spin

Hi and Welcome to the forum,

Probably not your problem but worth a look, i had a similar problem which turned out to be the fan on the graphics card not working properly, the card was getting pretty hot, since i change the fan it stopped crashing etc..

The graphics card is integrated into the Z68 chipset.

I do have a matrox PCIe graphics card I can try (and disable the integrated graphics)

[Edit: I can't use the Matrox card because it does not have an output resolution compatible with my monitor - I'll try my NVidia 8600GT later...]

If its integrated then it probably isnt that
