        Kernel driver in use: snd_hda_intel

My system is debian testing with self-made kernels. The system is working as
Dom0 under Xen 4.1.

Since kernel 3.6 the drm radeon driver freezes the system after some time.
This time can be 10 minutes or some hours. Since the system is completely
frozen I don’t know if there are error messages displayed, but the log
contains nothing. Simply pressing the reset switch won’t reset the graphic
card (no output), I have to switch off the system to get the card working
again.

Did you also change the userspace drivers (mesa, xf86-video-ati)?  If

This system is a console system, X is only used sometimes. So while there may be updates of other components (it is Debian testing after all) the problem occurs in console mode without running X or mesa.
And rebooting the old 3.5 kernel solves the problem.

you only changed the kernel version, can you bisect?  If you updated

Not without some help,. I’m no programmer. You probably mean I should test different git commits?
