capture-example.c crash on close_device()
Hi,
I have compiled kernel 2.6.30 from kernel.org, and I have also compiled capture-example.c from the mercurial depository. These work on laptop hardware, but on my DM&P e-box 2300SX (with vortex86 cpu), capture-example.c crashes the system. Complete lockup, no keyboard, etc. I turned on all debuging in gspca_main, i.e. options gspca_main debug=0x1FF. I also put print statements in capture-example.c in main() before each function call. Here is the output below. Has anyone had this problem?

Hans,
What do you think is causing this? pac207 driver.

I'm still having trouble with capture-example.c completely locking up my system. The same os image on other hardware works fine. Where do I start looking? What can I do to debug this issue?
