>> my system details:
>> T520 ThinkPad
>> 6 Gb RAM
>> i7 quad-core CPU @ 2.8GHz
>> RME Hammerfall DSP Multiface on ExpressCard adapter
>> PlanetCCRMA on FC16 (x86-64)
>> my observations so far:
>> kernel 3.1.0-7.fc16.x86-64 ----
>> jack runs reliably down to 64x2
>> hdspmixer runs reliably
>> kernels 3.2.17-1.rt28.1.fc16.ccrma.x86-64.rt AND 3.3.7-1.fc16.x86-64
>> jack starts, but locks up very quickly
>> hdspmixer locks with error: "HwDep ioctl failed. Metering stopped"
>> any help sorting this out would be most welcome... let me know if there are error messages or other console output which would be useful!

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!
