Hi,


For some weeks now, i'm running a xen-4 based system, which i want to take 
over the tasks of my previous xen-3.2 based server.
One of the things i used to do with my 3.2 system, was running a mythtv server
inside a pvm with ivtv based hardware. This seemed to work fine with xen 3.2.

Trying to get this to work with xen-4, i don't seem to have much success... 
older versions of the kernel would lock-up (well that's what you get for 
trying bleeding edge, i know), but now it seems to boot fine.
However, as soon as i try to record something from /dev/video0 (e.g. using cat 
/dev/video0 > tmp0.mpg), i get a ivtv0 DMA TIMEOUT message on my console.
When i break off the action (after about 30 seconds or so), the tmp0.mpg file 
has a 0 size, indicating nothing at all was recorded.

Is there something i can do about this? Or am i just asking too much of the 
system right now? I also tried various swiotlb options (on 3.2 those were 
absolutely necessary), but to no avail.

Any hints/tips would be very much appreciated!


Regards,
Mark.
