Subject: [video4linux] oopses with n*gratv
X-MARC-Message: https://marc.info/?l=linux-video&m=90242147417169

Hi!

I get the following oops-cascade, if starting n*gratv multiple
times (perhaps bttv related?):

The strange thing is, that it is always the same wait-queue
corruption, not a random memory corruption.

The following oopses are fatal - a corrupted waitqueue is always bad...
