hi all,

i have some issues with playback on one of my machines with different
kernels, having my rme hammerfall hdsp connected via a cardbus/pci
adapter card.

after some time (between a few seconds and several minutes) of flawless
playback, the system completely freezes, magic sysrq keys are not
functional either ... the freeze occurs with rt and non-rt kernels,
with jack running with and without realtime scheduling.

i have the suspicion, that it is related to the combination of the hdsp
with the cardbus controller of the adapter card ...

the interesting part of lspci is:

the irq 17 is used by these two devices only. i am not sure, how to
proceed debugging this, since i cannot get any useful debugging
information ...

thnx, tim
