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

In-Reply-To: <m1fx3befxr.fsf@fess.ebiederm.org> (Eric W. Biederman's message of "Sun\, 04 Apr 2010 02\:16\:00 -0700")
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.
