I am also getting random lockups and not sure why. Darn things are tough 
to nail down. I have nothing on irq9...everything is steering through 
irq11. I left mythtv running over night and it locked up (picture froze 
nothing else happened) and mythbackend reported "Backend stopped in 
RequestRingBufferBlock", which tells me my PVR250 prolly stopped 
encoding tv? I restarted tv fine after that. I am still having the issue 
where I cannot Escape from the "Recorded Programs" window. Using CVS 
from 4-20.
