Subject: Re: [PATCH 3/4] Revert "x86: disable IOMMUs on kernel crash"


I guess I should add the place where I have serious test results for with
a gart is on 2.6.29.  Where there isn't that iommu shutdown and I don't have
problems with it.

So my experience is that touching the gart in machine_crash_shutdown is
unnecessary.
