get_dirty_pages returned -2

Hello Devs!

On my haste to try new patches and stuff I got this error message looping
and using 100% cpu when starting vista as guest.

My host is a linux 2.6.22.1-cfs-v19 #1 SMP

So I have the cfs scheduler patchs in.

I have build kvm-33 on this new kernel.

I dont get this get_dirty_pages returned -2 when starting xp guest.

I am starting vista with those params.

kvm -cdrom /dev/cdrom -boot c -hda disks/vista.qcow2 -localtime -m 512 -net
nic,model=ne2k_pci,macaddr=00:00:00:00:00:01 -net tap,ifname=tap0 -std-vga

Vista was running within kvm-29 and kernel 2.6.21.3 without the cfs patch.


I found nothing about this error in the tracker.

Any recommendation that I may try? Or some more information that you need?

Thanks!

-std-vga is known broken.  Avoid this switch and all will be well.
