Hi Nick
Thanks for your help! it seems to me that the problem wasn't the ivtv driver
after all! I changed the PCI slot for the PVR-150 TV card and verified that
it changed the IRQ address using lspci -v as you sugested. The PVR-150 got
installed on IRQ 19 after this move, and it was the only board using this
IRQ. After booting the PC (still with irqpoll defined) it seems to be
working. Then I removed irqpoll and rebooted, and an arror apear on dmesg:
[ 55.249820] irq 21: nobody cared (try booting with the "irqpoll" option)
[ 55.249830] Pid: 5930, comm: xkbcomp Not tainted 2.6.24-19-generic #1

[ 55.249957] =======================
[ 55.249959] handlers:
[ 55.249960] [<f95f7430>] (via_driver_irq_handler+0x0/0x1c0 [via])
[ 55.249967] Disabling IRQ #21
IRQ 21 is only used by the onboard video card (lspci -v output):
01:00.0 VGA compatible controller: VIA Technologies, Inc. S3 Unichrome Pro
VGA Adapter (rev 01) (prog-if 00 [VGA controller])
Subsystem: Micro-Star International Co., Ltd. Unknown device 7312
Flags: bus master, 66MHz, medium devsel, latency 32, IRQ 21
Memory at f0000000 (32-bit, prefetchable) [size=64M]
Memory at f8000000 (32-bit, non-prefetchable) [size=16M]
[virtual] Expansion ROM at f9000000 [disabled] [size=64K]
Capabilities: [60] Power Management version 2
Capabilities: [70] AGP version 3.0
Before I change the board location, the same IRQ (IRQ 20 at that time) was
shared by the onboard video card and the PVR-150, and the crash resulted in
disabeling the IRQ20, afecting the PVR-150 because it used the same IRQ.
Now, as it is only used by the video card, the PVR is not afected. So this
seems a problem with S3 Unichrome driver and not ivtv as I initially
suspected. As I don't have a monitor connected to this PC (its my media
server, running a mythtv backend and streaming media to clients) I don't
know if there is a problem with its VGA output (the pc is in a 'tecnhical
closet' under the stairs, and it is not easy to put there a monitor). I hope
this might be useful to someone with similar problems ;-)
