Bug#604604: qemu-kvm: vm entry failed with error 0xffffffff; kvm_run returned -22

thanks

Hello again.

After a bit more testing it turns out this problem is
somehow specific to debian 2.6.32-5-686-27 kernel,
it does not occur on upstream (kernel.org) kernel
even when not applying the mentioned patch (which
went into upstream -stable just a few days ago,
but which was in debian for quite some time already).

Stock kernel - with or without that patch - works fine.
amd64 Debian kernel works fine too.  But Debian 686
kernel immediately returns that ugly -22 to every
kvm_run().  At least here on a CPU similar to your
(mine is Turion TL-52, which is of the same generation
as 4400+ you're using, with the same problems).

I'm not sure yet if it's specific to svm (amd) or
general.
