The problem didn't seem to be fixed by Lee's workaround after all.
Anyway, I recently migrated to Lucid and assumed bu the fast boot that
the problem was gone. However, my syslog says:

May 16 19:18:51 Internetdatorn kernel: [   17.560017] tda1004x: timeout waiting for DSP ready

May 16 19:18:51 Internetdatorn kernel: [   17.620686] tda1004x: firmware upload failed

Contrary to in Karmic, it doesn't seem to cost me much time, though.

Status in “mythtv” package in Ubuntu: Incomplete

Bug description:
Binary package hint: mythtv

MythTV causes problem with DVB-T card firmware. Symptoms are as follows:

1) After mythtv installation everything works fine for many restarts (few days)

2) Suddenly, firmware is not loaded. dmesg gives 
tda1004x: timeout waiting for DSP ready
tda1004x: found firmware revision 80 -- invalid
tda1004x: firmware upload failed

3) Uninstall and reinstall of mythtv package revert this state so card (and mythtv) is working again well. dmesg gives
tda1004x: found firmware revision 20 -- ok

I repeated this 1-2-3 cycle three or four times since karmic-koala install.
