Brand new ASRo Pro3 Gen3 with a 3.3GHz i5 2500 and 8GB RAM, BIOS updated to 1.20 (12/16/2011) Running Fedora 16 x86-64 with all latest patches (kernel version is 3.1.9-1.fc16.x86_64) 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) - Power cycle required to reboot 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
Created attachment 72100 [details] /var/log/messages the kernel does not oops
Created attachment 72101 [details] Xorg log
I can now confirm this happens with a vanilla 3.2.0 kernel
Definitely i915 related - I added a PCIe nVidia card and the machine ran perfectly stable. As soon as I took it at and reverted to onboard, the freezing started immediately Also, I'm actually running an i5 2500K, not a 2500. That's important as the 2500K has the Intel HD 3000 graphics core while the 2500 has the HD 2000 core I've tried adding i195.semaphores=1 on the kernel command line but it still hangs I also tried compiling the i915 module without KMS but that resulted in un-accelerated graphics
I've recently had a problem with an AsRock mainboard. As it turned out, their voltage control of the integrated GPU was buggy. Setting the voltage to "fixed 1.5V" instead of "auto" resolved the issue.
I now think this is a Motherboard and/or CPU issue - Crashing occurs in Windows 7 and have also had a hang when using an nVidia G210 PCIe card
