Hello,
I'm trying to use a Hauppage HVR-950Q ATSC tv stick with a Cubox-i running
geexbox.
It works great, until it doesn't. After its been up and running for a few
hours (sometimes minutes), I start to get kernel OOPs, example pasted in
below. The 950Q generally doesn't work afterwards.
This is a 3.10.30 kernel, that I believe the Cubox is somewhat tied to for
other driver reasons.
I haven't seen any such problems if the HVR-950Q is unplugged.
Any advice on tracking this down would be appreciated.
Carl
