Kernel 2.6.18-1.2200.fc5 crashes too when the webcam is taken off.
hmm, it does this even if the camera isn't in use by any application ?
I see one area of suspicious code in the driver, but that should only be
triggered if something was trying to capture from the device at the time.
boot 2.6.18-1.2200.fc5 -> plug the webcam in -> wait 5 seconds ( not even starting
the webcam app) -> plug out -> hang
So it crashes when not used.

Updated my desktop hardware to Asus m2npv-mx mobo and Athlon 64 x2 +3800 cpu.
Intalled fc6 x86_64 version and updated to kernel 2.6.18-1.2849.fc6.
Crashing continues. However with this kernel the system stays up for about 50%
This was reported to bugzilla.kernel.org as well. Patch available. :)
Kernel 2.6.19-1.2895.fc6 don't crash anymore. Should we close this bug?
