[LAU] problems with hdsp multiface

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 [ 2618.540382] RME Hammerfall DSP 0000:16:00.0: enabling device (0080 -> 0082) [ 2618.540555] ACPI: PCI Interrupt 0000:16:00.0[A] -> GSI 16 (level, low) -> IRQ 16 [ 2620.541147] ALSA /home/krgn/alsa/alsa-driver-1.0.18a/pci/rme9652/../../alsa-kernel/pci/rme9652/hdsp.c:659: Hammerfall-DSP: no Digiface or Multiface connected!

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
