Xawtv or cpia-0.4.4 problem?

[Hannu Martikka]

Hi!

I've been running xawtv-3.0.2 and cpia-0.4.4 for a while (~1-2days).
Then the xawtv disappeard. See dmsg output below. 

Any ideas whether this is a problem in cpia driver or xawtv?
The cpia_pp and cpia modules are still loaded, but I cannot start new
xawtv (/dev/webcam is link to /dev/video1):

This is xawtv-3.02, running on Linux/i686 (2.2.12-20)
visual: id=0x20 class=4 (TrueColor), depth=16
x11: 1280x1024, 16 bit/pixel, 2560 byte/scanline, DGA, VidMode
can't open /dev/webcam: Device or resource busy
waitpid: No child processes
v4l-conf had some trouble, trying to continue anyway
open /dev/webcam: Device or resource busy
can't open /dev/webcam: Device or resource busy
waitpid: No child processes
v4l-conf had some trouble, trying to continue anyway
open /dev/webcam: Device or resource busy
no video grabber device available

And as expected I cannot unload cpia_pp nor cpia modules.
But I can still use /proc/cpia/video1...
