I had to consult this wiki already multiple times (every time I get a new box...)
It's ok, but there is not really a solution. Currently I have one pci-card
and a rtdm driver. I got my unshared realtime IRQ after disabling the soundcard.

At the end of the year I need to be able to use three of these cards and
five realtime serial connections in one machine. I already have sleepless
nights ;-) and hope I understood something wrong...

AFAIK with 2.6.31 "threaded IRQ's" were merged to mainline. Would it be possible
now for IPIPE to pass down the IRQ's to linux so that the IRQ is handled, but
the IRQ-Thread is not started ? Or something like ?

Regards Stefan
