Hi,
I sent this report to the developer of the driver of the Philips cameras
and I was informed that the problem is USB related.
Thus, the oops report goes to you :)
Thanks in advance,
simos

Subject: Linux Oops: PCA645VC/EU, kernel 2.4.12, versioning OFF
Hi!
I would like to report an Ooops message.
(I tried earlier with module versioning ON and I got the same problem.
I believe with the non-binary module version, module versioning can be
left on. Anyway, in this report, module versioning was OFF.)
The information requested from the Support page:
a. kernel: 2.4.12
b. no other patches applied
c. 00:07.2 USB Controller: Intel Corporation 82371AB PIIX4 USB (rev 01)
(from lspci)
d. trace file (included)
e. the webcam was working in the 2.4.[23] era with the binary drivers,
this is my first attempt with the stock 2.4.12 PWC support.
I have the PCA645VC/EU connected on the box when I boot the machine.
In /var/log/messages, I get:

(the USB controller is sharing IRQ with the network card. Could that be
the problem?)
Running ksymoops on the above Ooops message, I get:

(hi. these are correct. --simos)
Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.
