Re: [PATCH v10 0/10] iommu/vt-d: Fix intel vt-d faults in kdump kernel

Bad news, I rebuilt a kernel with your patchset on 4.0.0+ (this commit
f614c81). Now dmar fault is  seen again.

The lspci log and kdump log are attached, please check:

[ ~]$ cat /proc/cmdline 
BOOT_IMAGE=/vmlinuz-4.0.0+ root=/dev/mapper/fedora_dhcp--128--28-root ro
