Hi, it's me again :)

It looks like that the bug i'm experiencing is caused by saa7146_core.c's 
saa7146_wait_for_debi_done function.
I didn't like to install 2.4 series yet ;) so i digged around in the
source code on my own. Maybe i'm completly wrong, but i think i tracked the bug to
that particular function.
It looks like the firmware is never written into the cards DRAM, as the
av7110_debiwrite (in av7110_hw.c) function fails everytime on
wait_for_debi_done.
So the firmware is actually never written into the dram, or am i
completly wrong here ?

here's the dmesg output with some debug-statements added by me (just included the last block,
but output is the same for every other block that has to be written):

right now, i'm not quite sure how to go on, so i thought i might contact
you 

cheers and thanks for your help
