I had to cvs upd -D 2004/12/20 dvb_frontend.? and recompile to get it work
again...

However now instead of seeing the bitblitmap timeouts I get tons of timout
waiting for COMMAND idle errors and *NEW* busy MSQ QUEUE

[...]
dvb-ttpci: __av7110_send_fw_cmd(): timeout waiting for COMMAND idle
dvb-ttpci: av7110_send_fw_cmd(): av7110_send_fw_cmd error
dvb-ttpci: av7110_fw_cmd error
dvb-ttpci: __av7110_send_fw_cmd(): timeout waiting for COMMAND idle
dvb-ttpci: av7110_send_fw_cmd(): av7110_send_fw_cmd error
dvb-ttpci: av7110_fw_cmd error
__av7110_send_fw_cmd: timeout waiting on busy MSG QUEUE
[...]

well doing a long term experiment...

Soeren.
