did some observing...
when i put snd_hdsp in the RTIRQ_NAME_LIST in the rtirq config, neither
priorities nor IRQs change. however...
for ALL kernels under which jack fails:
/etc/init.d/rtirq status
shows irq/19-snd_hdsp AND irq/19-firewire
and for the one kernel under which jack works:
/etc/init.d/rtirq status
shows irq/19-snd_hdsp and a DIFFERENT irq for firewire
this seems significant.
and... how can i ensure firewire gets a different irq?
for now, i'll try killing the firewire module, since i don't use anything
firewire at the moment.
cheers!
