Hi Thiago,
The best way forward for this kind if issue is to:
1/ Open a bug against the Debian linux kernel.
2/ Provide a patch to fix the issue, attached to the bug.
Bug keep this in mind when doing so: You need to test under *debian*,
and not just under Ubuntu. From the launchpad bug you've opened, it's
looking like you've had the issue in Ubuntu, and there's no way to tell
what will happen in Debian. Also, you issue seems related to kvm/qemu,
and not only to the kernel.
Cheers,
Thomas Goirand (zigo)
