Hi,
I hope this is the right list to post this on - if it's not please
direct me to the correct list.
I'm having a strange problem with tuning and locking some channels on
this card. After a cold boot, it will always lock to any channel, but
after a while (20 minutes or so) it will refuse to lock to two
particular frequencies, while the other 3 are fine. Immediately cold
booting (ACPI power off, wait about 10 seconds, hit the power button)
will result in being able to get a channel lock again. I don't think a
warm boot fixes the problem (I will test next time it refuses to lock).
When I tzap to one of the affected channels after cold booting, the
signal column creeps up until it hits ffff after a couple of minutes
(see end of email). A bit later, the snr column starts falling and the
ber column starts rising, and eventually the channel lock gets lost.
When I cold boot at this point, I can get a lock straight away.
I'm also getting a heap of error messages
cx88[0]/2-mpeg: cx8802_timeout
in my kernel logs.
Kernel is 2.6.20 (Gentoo), and I'm using the in-kernel drivers.
I'm willing to send any debug output or config files, and apply any
kernel patches - just point me in the right direction.

and ber rising)
