I am experiencing a kernel oops when trying to use a Hauppage USB Live 2
frame grabber. The oops is below.
The system is a SOC 260Mhz Broadcom BCM47XX access point running OpenWRT.

Linux anchor 3.0.3 #13 Sun Dec 4 08:04:41 PST 2011 mips GNU/Linux
The OOPS could be due to the limited hardware or something else. I'd
appreciate any suggestions for making this work. I was hoping with
hardware compression I could make it work on this platform. I am
currently using a Hauppage USB Live (saa7115 based) with no problems but
with limited resolution.
