The CX25843 chip on your PVR-150 isn't responding properly.
The most likely cause is the CX25843 chip on your PVR-150 is no longer
working.
You can turn on some debugging as root to see what the cx25840 module is
reading as a device ID from the CX25843 chip:
# modprobe -r ivtv
# modprobe -r cx25840
# modprobe cx25840 debug=1
# modprobe ivtv debug=0x203

You can try a few things to see if the PVR-150 card will work again:
1. Don't load proprietary drivers like the fglrx module listed in your
output above. If they accidentially corrupt the window into CX23416
memory space or register space, or corrupt ivtv internal data
structures, then things won't work.
or
2. Pull out *all* your PCI cards, blow the dust out of *all* the slots,
reinsert the cards, and test again.
or
3. Blacklist the ivtv module in /etc/modporbe.conf.d/, and modprobe the
ivtv module later after the boot sequence is complete. The PCI bus
register accesses for the I2C bus transactions may not be reliable on
that motherboard when the PCI bus is very busy.
or
4. Test with a Windows install on the machine.
or
5. Test the PVR-150 in another machine.

Andy
