When X server goes up, fwohci device starts to eat enormous number of interupts per second (as shown by 'systat -vmstat 1') rendering system terribly slow. BTW: 5.1-RELEASE had also problems on this maschine as a camera connected via firewire was able to crash the machine when the camera was turned on. This seems it is OK now and I'm able to attach the camera on the fly and grab video using fwcontrol without any problem. Except for the tremendous number of interrupts per second slowing down whole machine when X is running. Any ideas?
