Sure, you basically reverted my patch.

You are not the first to report a problem caused by this patch.

This patch is known to have uncovered some driver bugs.

We are not going to revert it. We are going to fix the real bugs.

Thanks

Agreed, we are looking into issue Thomas.

any news from the Intel labs what might be going on here?

We started seeing those hangs on "MSI B85M ECO" boards, too,
though it's way more sporadic there.

I have not heard anything, so I have added Aaron Brown to see if he has
any additional information.
