[arch-general] Debugging kernel panics (ATI Catalyst related?)
After the last updates, I was getting a kernel panic at reboot; hard-resetting and then powering on again and it seems to boot fine. I suspect the problem has to do with the ATI Catalyst driver, as the panics occurred when rebooting after upgrading or downgrading the driver. I originally upgraded to 12.9, but rolled back to 12.8 after discovering that 12.9 broke my screen brightness keys. I also had to roll back Xorg to 1.12 because Catalyst doesn't support the new Xorg yet. Both times I rebuilt the module and (just to be sure) the kernel image before rebooting. I rebuilt them again once the system was back up, rebooted, and it worked. Any ideas how to debug, seeing as this just sort of popped up out-of-the-blue? If the kernel even logs a panic, where do I find it so I can figure out what caused it?

I myself am suited with Radeon opensource drivers for all my needs - GoogleEarth and Blender, you should try it. As for your Catalyst specific glitchs it might be a better place to post your issue at the AMD / ATi Bar & Grill at the forums since that thread is created and maintained by Vi0L0 himself, the Catalyst packager and supporter: https://bbs.archlinux.org/viewtopic.php?id=57084

I couldn't get the open-source drivers to work, all I got was a blank screen, and that was from fresh install. I had a look at the road map for the Xorg drivers and I got the impression that work on the driver that supports my cards is far from complete. The only reason I'm suspecting Catalyst is because those were the updates done prior to the panics, and I can't replicate it now.

I didn't follow the thread. Do you use a xorg.conf? Perhaps you can use my xorg.conf as a template.

However, on Arch I get the graphics working with the wanted frequencies and resolution, 3D is working too (tested with GoogleEarth), unfortunately I run into audio xruns hell, perhaps not related to the graphics, but it shares the IRQ with the audio card. For Ubuntu I'm limited to a max of 1024x768@60Hz at the moment, but until now I didn't notice audio issues. Once I switched from the integrated ATI to a NVIDIA card and now I switched back to the onboard ATI ;). Sometimes it's less time consuming to switch graphics. I got my secondhand NVIDIA "for a song". Current Catalyst doesn't support my graphics, an issue I never got for old NVIDIA cards. I made better experiences with NVIDIA than with ATI, I anyway switch back to ATI at the moment ;).

I forget to ask, if you still have the error logs (/var/log/) may be you want to post them to pastie.org or any similar service.
