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.
