Subject: kernel oops with TT S2-3200
Newsgroups: gmane.linux.drivers.video-input-infrastructure
Date: Saturday 22nd May 2010 23:15:45 UTC (over 7 years ago)
I'm running debian testing on an AMD Sempron box, kernel 2.6.32-3amd64, 
with a TT S2-3200.

I've been setting the box up as a Myth TV backend.

The stock kernel drivers for the S2-3200 appear to work (to the extent 
that I was able to scan for channels in Myth TV) however I was getting 
errors during channel scan (fec_inner not supported in the mythtv log) 
so I updated to v4l-dvb tip to see if this error disappeared.

I now get a kernel oops on loading budget_ci as below.

This is changeset 14873:b576509ea6d2.

I see on the wiki that there is an hg bisect utility that I can use to 
narrow down where this has been introduced. Would it be useful I do so?

Would any more information be useful?
