Hi Gerd, I haven't been able to capture a new oops - but I continue to get
the usual hard hangs. Here's the output before a hang, captured using
netconsole. The app is xawtv, using PAL composite video. I've attached
the xawtv verbose output (for a different run). The time between starting and
hanging was around one minute. I don't see anything strange...

All the best,

Duncan.
