Severity: critical
Justification: breaks the whole system
When I try to capture using a program such as webcam-server, I don't
get any image. Even worst, when I kill webcam-server, I get a kernel
oops and need to reboot my system.
Can you please send me the camera model and USB descriptors? Also,
could you try reproducing this problem with a vanilla debian kernel?
Thanks.
