[linux-audio-user] RME Digi96/8 PST and jackd watchdog timeout

I just bought a RME Digi96/8 PST soundcard and installed it on my
computer. Once rebooted, info in /proc/asound/cards seems to be
correct:

$ cat /proc/asound/cards
 0 [CK8S ]: NFORCE - NVidia CK8S
                      NVidia CK8S with ALC850 at 0xfc001000, irq 193
 1 [PST ]: Digi96 - RME Digi96/8 PST
                      RME Digi96/8 PST at 0xfb000000, irq 201
 2 [UM1 ]: USB-Audio - UM-1
                      EDIROL UM-1 at usb-0000:00:02.0-4, full speed

I am forcing index numbers via /etc/modprobe.d/sound so mobo's
internal soundcard is the default device.

If I tell xmms to use ALSA and output hw:1,0, it works nicely and RME
plays sound. But if I tell jackd to use that same output, it gets
killed by the watchdog!

It's the same no matter if I change frames/period, periods/buffer,
priority, timeout, input and output channels, it's always the same.

I'm finding pretty difficult to find a PCI slot in my mobo which
allows me to use an isolated IRQ for the RME, if anyone thinks this
could be the problem..

I am running vanilla 2.6.17 with Ingo Molnar's rt8 patches. I can post
my kernel config if useful.

Any ideas will be very welcome so thanks in advance.

Cordially, Ismael
