1.0.25-1.fc16.x86_64

but i'm not really sure if that's the culprit, or if it's a kernel thing that's throwing the hdsp, and the hdspmixer fail is just a symptom of that... on some other systems (with older kernels, mind you!) 1.0.23 was better for hdspmixer, so *maybe*. however, i do know there's still something else going on, because jack (jack2, btw) fails even if i haven't touched hdspmixer since a reboot.

you haven't tested *RME hardware* on *that* setup (fc16 x86_64 + rt kernels on the old Lenovo T61)?

hmmmmm.... what would you recommend as my next step?

thanks, fernando... cheers!
