I am getting panics shutting down for a few days now. The only
significant changes I remember are 10.1-RELEASE/amd64 (updated from RC4,
RC3, ...) and nvidia-driver-340.46 (updated from 331.67_1). Since I had
no problems with any 10.1-RCx, I suspect nvidia-driver to be the problem.
nvidia-driver-340.46 was forcibly installed alongside libglesv2-10.3.2
and libEGL-10.3.2, which are required by kde-workspace-4.11.13. I tried
with the conflicting files present from any of the two packages and got
a panic in both cases.
The panic can be triggered pretty reliably by "service kdm4 stop" and on
any shutdown or reboot with Xorg (+kdm4) still running.
Before I start testing without nvidia, trying to downgrade
nvidia-driver, trying without kdm4, etc.:
Is this problem known? Can the new conflict have anything to do with the
problem? Is there anything useful in the panic message I wrote down below?
