Package: src:linux
Version: 4.9.2-2
Severity: normal
Using the same USB webcam as from the crash reported in
https://bugs.debian.org/852738, i plugged it in again after rebooting
into 4.9.0-1-amd64 (version 4.9.2-2). While i didn't get the null
pointer dereference, i got several unusual messages ("Warning!
Unlikely big volume range (=3072), cval->res is probably wrong") on
insertion, and then 5 minutes later i yanked the camera and got a
series of warnings on removal that all seem to be related to sysfs
groups:
