It looks like this was fixed upstream by:

commit 7b292b4bf9a9d6098440d85616d6ca4c608b8304
Author: Andrew McGregor <andrew.mcgregor@alliedtelesis.co.nz>
Date: Mon Jun 13 11:31:31 2011 +1200

tty: fix "IRQ45: nobody cared"

The symptom mentioned here (unexpected IRQ) is different but I think the
underlying bug is the same.

Can you test the attached patch against the stable kernel? Instructions
for this can be found at:
<http://kernel-handbook.alioth.debian.org/ch-common-tasks.html#s-common-official>.
