Re: RTAI and comedi on a Power Mac G4

Hello,

I have not (yet) worked with Comedi and therefore I can only help with
RTAI (PowerPC) issues. To work-around the depmod problems you could try
to load the modules manually (with insmod). What function do you use to
reenable the interupts in your (deferred) ISR. In case it's
rt_enable_irq() try to replace it with rt_unmask_irq().

Hope it helps.

Wolfgang.
