I need help to solve this strange problem.
I have into the same pc a pvr-150 and a nexus-s. To fire-up the nexus-s i need
to compile my own kernel. I have compile the ivtv driver to. When i boot the pc
with the distribution kernel the pvr-150 work fine. When i boot the pc with my
own kernel the nexus-s work but not the pvr-150. There's the output of the
logs:

#alias tveeprom tveeprom-ivtv
#alias tuner tuner-ivtv
#alias msp3400 msp3400-ivt
I have deseable the three last alias to manualy load the ivtv, tuner and msp3400
modules. I have also rename the tveeprom, tuner and tda9887 into the kernel
modules tree.
I have also put the definition of the ivtv driver at the first or at the end of
the modules.pcimap.
There's the error message when i try to get status of the pvr-150:
#cat /dev/video0 >/test.mpg
cat: /dev/video0: Input/output error
