Hi,
I get crash on loading module on 2.6.16.20 kernel on modified Debian
system (Plutohome.com). After that crash camera works (it seems crash
happens after the main part), but if I let it to load automatically,
then booting process freezes....
Any hint how to tackle this one ? Is it related to kernel or some other
app, cause similar crash happens also with zpca50x (another usbcam
driver) ?
As far as I remember some time ago we also tried newest version, but
with same crash....
Thanks in advance,
regards,
Rob.

You can install pwc-source, it's 10.0.12-rc1, build the module and test
it.
