Re: 7-current. is it possible to compile?
@Ravna: I hadn't been aware of this problem before, thanks for the heads-up; unfortunately, there isn't much to go on in the email thread on freebsd-current (I think you were referring to the 'recent nvidia-driver trouble' thread), other than that it seems to be a panic at device teardown time.
Do you have a serial console setup that you could use to capture the panic? If not, does `cat /dev/nvidia0` (at the console, before starting X) reproduce the problem?
