[linux-dvb] cx88 Troubles

I am having difficulty tuning channels with my cx88 based card. I am
running a very recent mercurial checkout of v4l on top of an x86_64
build of the 2.6.20 kernel. When I attempt to digital channels I get
many instances of:

cx88[0]/2-mpeg: cx8802_timeout

in my dmesg log. Also scan prints:

>>> tune to: 569028615:8VSB
WARNING: filter timeout pid 0x0000
WARNING: filter timeout pid 0x1ffb

Unlike a similar problem experienced by another user in the past, I
appear to be receiving interrupts normally:

cat /proc/interrupts | grep "cx88\|CPU"
           CPU0       CPU1
22:       4367          0   IO-APIC-fasteoi   cx88[0], cx88[0], cx88[0]

Thanks for your help.
