Subject: Re: [PATCH 0/10] iommu/vt-d: Fix intel vt-d faults in kdump kernel

According to Takao Indoh's testing, seems adding flush after loading old 
irte and updating old irte does not fix the dmar faults.

According to Takao Indoh's log and your log, the faults happens while 
and after driver is loaded.  Maybe I am using incorrect code in 08/10.
