Here the first tests results:
vbox modules do not make a difference (tried rmmod vboxpci vboxnetadp
vboxnetflt vboxdrv and then kvm ...).
The trace.dat is about 60M, I could upload it somewhere, however I tried
looking at it and I'm reasonably sure it hangs here:

The rest of the log is about 5 seconds of d5 d5 d5 d5...
As for the bisect, I'm not sure of a good commit in the vanilla tree. By now
the only working kernel I have is a debian one.
While doing these test a suspect came to my mind: a difference between mine and
debian kernels is that I configure mine preemptible low latency desktop. Could
that be the cause?
