Hi, Ok, i just rebooted my system with this setting, Will start some recordings,Anyhow, what I would like you test is to provide 'noirqdebug' flag on your Linux kernel command line. That should take care of the 'nobody cared IRQ'. Please test and see if you your machine is more or less sluggish. and see how it behaves. I put a monitor in place, we'll see what happens. As far as i can see now,Also, please do run this: while (true) do sleep 10 cat /proc/interrupts | grep 16 done during the lifecycle of the whole machine. I am curious to see whether you also get an IRQ storm (or if it is just a trickle - which is OK) after launching the DomU guest. the radeon driver registers the IRQ, but doesn't seem to do much with itduring normal use (counter is still 0 after about 15 minutes running X now). Perhaps it is meant for opengl or some accelerated function, or my xserver is just not using the drivers full potential. Which makes it all the easier to see a storm should it occur ;-) Regards, Mark. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
