Thank you! I tested this patch, and it indeed fixes the problem. You may add: Tested-By: Askar Safin <[email protected]> Please, CC me with further patches, I will test them. Also, I will repeat that the bug doesn't happen if we have CONFIG_INTEL_IOMMU_DEFAULT_ON=y. So, probably we just need to patch all distro's configs to include CONFIG_INTEL_IOMMU_DEFAULT_ON=y (Ubuntu already does that.) On the other hand, if there is some deeper issue to fix, then, of course, I'm glad it is being fixed! Also, please, add some "Fixes" tag and CC stable to make sure this fix will be backported to stable kernels. For example: Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2") Cc: <[email protected]> Here I chose the initial git commit, because i915 always was in git history. -- Askar Safin
