Crash hunting in Radeon KMS
Me and some of my fellow Archers, are plagued by crashes when running latest mesa,libdrm,xf86-video, and kernel GIT while using radeon KMS. UMS is fine. It causes crashes (not kernel "oops") of the video driver ("no signal" on the monitor) and makes the machine unresponsive to keyboard or SSH.
We think that we've found a way to reproduce it in KDE SC 4.4:
Could you please take a look at the bug report and see if you can reproduce the crash? Please state your kernel/mesa/libdrm version and card.
Please help us find the bug responsible for the crashes.
Have you tried connecting a serial console or a net console?
Assuming that you have a second machine available to host the console, of course. But that way you'd be able to read any dmesg information, even when the local console stops responding.
