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.

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.

The cx231xx driver requires the cx25840 module. I'll wager you didn't
install it on your router.
I made sure the module was loaded; same thing. :-(
