[LAU] problems with hdsp multiface

[krgn]

hello list,

I have a x86_64 debian setup (lenny/sid) with rt-kernel and ran all of this
with a rme multiface mark 2 card. until today, that is when the card
suddenly stopped working. It fails with this error:

[ 2618.484513] pccard: CardBus card inserted into slot 0

the card is definitely connected though, so something else must be wrong
here. lspci -vv shows

Trying to narrow this down further and plugged the card into an older lappy
with debian lenny x86 on it where it works fine. I'm really puzzled by this
as it all used to work great yesterday and now it doesn't find the card no
more?? I also wonder how I can find out what exactly error -5 is. it seems
that -16 is when the firmware is missing, but this is not the case here. I
am really really puzzled as to whats going on as the setup worked flawlessly
until yesterday. the only thing that has changed since yesterday is that I
disconnected the unit from the computer, went out on a trip and reconnected
it.

does anyone have an idea what could be my problem here?

thanks in advance,

karsten
