--- Comment #23 from Mario Limonciello (AMD) (mario.limoncie...@amd.com) --- When you're doing your bisect you should explicitly look for any DMA mapping errors that are introduced with IOMMU disabled. BTW - please don't test with "iommu=off". To isolate AMD IOMMU specific issue you should use "amd_iommu=off". This will at least allow the use of software bounce buffers, which might have been the problem induced in Mediatek driver by running "iommu=off". -- You may reply to this email to add a comment.
