There are only 3 changesets to choose from.  It can only really be

hg: 23552:d7ad3e2f1119
git: df751b6da15afff1f87a68f63013dd96e9563047

"x86: fix ordering of operations in destroy_irq()".

Is it possible for your to run tests with the same dom0 kernel but 4.2
or unstable around these changesets?  Unless it can be proved to only be
a problem with 4.1, I suspect we may want to back out the change,
especially given the proximity of 4.3
