Subject: Problem pwc-10.0.12-rc1 oops


Hallo *!


Problem:
- after approximately 6h breaks motion/pwc.
  (s. dmesg)

- The installation makes with following guidance:
  http://www.seismo.ethz.ch/linux/webcam.html
  CONFIG_USB_PWC=m
  and overwrite module with version pwc-10.0.12-rc1

- not possibly the module to removed
  (s. rmmod)

- the pwc-modul (shipped with linux-2.6.16) does not work.
xawtv say: no way to get: 384x288 32 bit TrueColor (LE: bgr-)


Whats going wrong?

regards Torsten
