I didn't tweak the irq properties and I'm using the latest realtime-kernel

(linux-rt in the repositories), though the ati drivers still don't work with

it - I'd have never bought an ati if I had known that I would only be using

linux... Here's my output of cat /proc/interrupts:

I don't know what it means, but maybe there's some information for you in

there ;-) . If it's of any effect, I'm running a generic kernel right now and

the card's not connected, but the system is the same. There's

no /etc/init.d/rtirq on my system, so I can't provide that information...
