--- Comment #4 from Андрей Кольчугин
From SLE11 SP3 we know that the i915 DRM code on top of an IOMMU currently has issues. So we're awaiting a fix there, which hopefully will help here too then. Analysis of the 'dmesg' output running Linux kernel without Xen but with IOMMU on shows the following diagnostics:
[ 0.243871] dmar: DRHD: handling fault status reg 3 [ 0.243878] dmar: DMAR:[DMA Write] Request device [00:02.0] fault addr bf800000 [ 0.243878] DMAR:[fault reason 01] Present bit in root entry is clear [ 0.243926] PCI-DMA: Intel(R) Virtualization Technology for Directed I/O Device 00:02.0 is, obviously, graphics controller. Although Linux+VT-d doesn't lock up hard, screen is completely unreadable (color bars). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
