Hi,
I've found strange problem after upgrading from 5.1-RELEASE to 5.2-RELEASE
on my DELL Precision 530. 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?
Best,
Petr
