I'm using a Haupauge PVR-150 board in a Ubuntu 8.04 PC. Recently the board
stoped working (mythtv logs ivtv driver timeout everytime I try to use the
PVR-150), with what seems to me a crash related with the ivtv driver (see
below). The ivtv version is 1.1.0, as it can be seen with dmesg. At the end
of the system boot we can see the crash in the following report (dmesg
result), and this started happening everytime I boot the PC (after working
well for several months):

As it was suggested in the mythtv users group, I have defined irqpoll in
Grub, and this solved the ivtv driver crash (and TV started working again),
but I also noticed that later I started having a driver crash that seems
related to the ATA interface (never happened before starting using irqpoll).
So I suppose the best way is to remove the irqpoll option, but I need to
solve the ivtv crash.
What do you think it is causing the problem? Can it be because IRQ20 is
shared by Haupauge PVR150 and the onboard graphic card (Via S3 Unichrome)? I
saw somewhere that the PVR-150 doesn't behave well sharing the IRQ with
other boards. This is the result from the lspci -v where I can see that the
IRQ20 is used by PVR-150 and S3 Unichrome:

What do you suggest to solve this problem? Changing the PVR-150 PCI slot?
Any other option?
Thanks in advance
