[mythtv-users] 0.15 and PVR-250 only recording a few sec

[mythtv_user]

A bit more info --
when it dies I see
Spurious 8259A interrupt: IRQ7
ivtv: giving up waiting for DMA pending to clear

in /etc/log/messages

looks like a few others on this list and the ivtv list have seen this 
issue, but I didn't see any solutions posted (especially in the case 
where cat /dev/video0 > test.mpg works)
I tried dissabling usb, parallel port, serial ports, and ethernet in the 
bios
That didn't seem to help.
