Ah! This is the cause:
ivtv: Autodetected WinTV PVR 250 card (iTVC15 based)
iTVC15 is used for the PVR350 but apparently you also have one.
The interrupt that is active is the IVTV_IRQ_DEC_VSYNC interrupt, which should
only arrive on a PVR350 (with a decoder chip).
Also odd is this:
tveeprom: Hauppauge: model = 48012, rev = G310, serial# = 2600478
tveeprom: tuner = Philips FI1236 MK2 (idx = 10, type = 2)
tveeprom: tuner fmt = NTSC(M) (eeprom = 0x08, v4l2 = 0x00001000)
tveeprom: audio processor = MSP3445 (type = c)
tveeprom: decoder processor = Type 0x00 (type = 0)
The decoder processor (unrelated to the mpeg decoder on a PVR350) is 0. What
chip is on your board? AFAIK it should be an SAA7115.
Can you edit ivtv-driver.c: search for IVTV_IRQ_DEC_VSYNC and remove it from
the mask. Now try again and let me know if the problem is fixed.
Chances are that you still get interrupts in, but the errors should hopefully
be gone.

There are 250 cards known to have itvc15 chips, the early ones, I have
one of these, they should be checked for in the driver, but sounds like
somethings odd there.
Thanks,
Chris
