1. Plug in webcam or boot with web cam pluggen in you get a kernel panic:

kernel panic: Aiee killing interrupt handler!
in interrupt handler - not syncing.
That would be a kernel problem, and not related to usbview.
The qa0322 ISOs are quite stale now. The kernel in this cut was 2.4.2-0.1.32;
we're up to 0.1.40 now and I *think* this may be fixed. Please re-try this on
the qa0328 ISOs that were delivered to the beta web-site last night and report
back whether it's still broken or not. Thanks!
I would appreciate if either oops was decoded, or
the oopsing kernel was identified (cat /proc/version).
BTW, the call trace looks as if the requestor typed
it in. It is error prone, not to mention a tiring job.
It is much more reliable and productive to use
a serial console instead.
perhaps you do not realize that "RH 7.1 RC 2 QA0322"
ships with *SEVERAL* kernels and I need to know which
particular one you were using. At the moment I do not
even know what driver your webcam uses (ov511, ibmcam, or other).
It is unheard that a vendor wants to fix a bug and a customer
does not. The Universe is coming to an end!
I am sorry. I thought I updated this bug. This bug was fixed with a later
release and is still working in the released version. You can close this bug.
