[pvrusb2] udev error? /dev/video0 and /dev/video missing

[Daniel Roth]

My linux kernel is 2.6.15-26-amd64-generic.

I used the following code to get V4L:  sudo cvs -d
:pserver:anonymous at cvs.linuxtv.org/cvs/video4linux co v4l-kernel

And no, I didn't use ivtv.

Mike, thank you so much for your help.

Well the kernel oops is definitely not a good sign.  Probably udev removed 
those devices when the driver died due to the oops.  Looks like the 
saa7115 caused the explosion.  Clues that will help here include what 
kernel you are running and where you got V4L from if you're not using 
what's already bundled in the kernel.  Also, did you use the "ivtv" 
modules in the pvrusb2 driver - you don't want to use them for pretty much 
any recent kernel version these days.  (I suspect the answer to that last 
question is "no" since they won't otherwise compile with anything newer 
than roughly 2.6.15, but it's worth being sure.)
