I am not much wiser, but I have a few more backtraces. I tried removing
various modules and changing various config options to see if they have
any effect. It is impossible to be certain, since the panic is not
completely reproducible, but I think the culprit is drm.ko. Any idea
how I can confirm or refute this suspicion? Here are the backtraces,
for what they're worth.
