[mythtv] Mythtv and kernel 2.6.25

[Paulo Cavalcanti]

Hi,

I am having problems to make mythtv work with kernel 2.6.25 (Fedora 8).

The problem seems to be my capture card, a Prolink Pixelview.

Myth starts just fine, but the first time I choose LiveTV,
mythfrontend becomes unresponsive. If I press 'esc' to go back,
it takes 30 seg to return to the main menu, and I have to kill the frontend.

After that, mythbackend can not be restarted or killed (there is a defunct
myth process running).
If I reboot the computer, the partitions are busy (can not be unmounted
cleanly).

Going back to kernel 2.6.24, everything works just fine. I have been using
this card for years
with myth just fine. I can also play TV using mplayer without any issue on
kernel 2.6.25.
Therefore, the problem seems to be really the interaction between mythtv and
my card.

This is how my card is detected (on kernel 2.6.24, if this make any
difference):

Jun 10 21:57:40 cascavel kernel: bttv: Bt8xx card found (0).
Jun 10 21:57:40 cascavel kernel: ACPI: PCI Interrupt 0000:04:02.0[A] -> GSI

Jun 10 21:57:40 cascavel kernel: bttv0: i2c: checking for TDA7432 @ 0x8a...

Myth log does not show anything special, when the problem occurs, but:

QServerSocket: failed to bind or listen to the socket
2008-06-10 21:27:26.852 Failed to bind port 6543. Exiting.

Any help would be really appreciated.

Thanks.
