in interrupt handler - not syncing.

Comment 1 Trond Eivind Glomsrxd 2001-03-29 16:03:07 UTC
That would be a kernel problem, and not related to usbview.

Comment 2 Glen Foster 2001-03-29 19:40:37 UTC
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!

Comment 3 Pete Zaitcev 2001-03-31 05:22:13 UTC
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.


Comment 4 Pete Zaitcev 2001-04-06 23:28:27 UTC
Bryan,

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!

Comment 5 Bryan Leopard 2001-05-16 18:35:13 UTC
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.
