Title:
Lenovo e73 USB webcam problems
Status in linux package in Ubuntu:
Incomplete
Bug description:
I'm experiencing problems with USB webcam on Lenovo e73 with Ubuntu
16.04.2 Xenial 32bit.
Originally with 4.4 connecting the camera often resulted in complete
hang of the system (apparently not even SysRq worked, though I did not
test that personally since it is a system I'm administering remotely
for a family member). There was always a null pointer dereference just
before the hang, so I suspect that is the culprit (see the attached
kernel log).
After some updates the system no longer hangs. I suspect this was
fixed by going from linux 4.4 to 4.8. However, the webcam still often
doesn't work and most application just return error. This is usually
fixed after several tries, but sometimes it is necessary to reboot
computer. Updating BIOS didn't help. The kernel logs still contain the
same null pointer dereference with exactly the same stack trace for
both 4.8 and 4.10.
