Hello Christoph,I was able to compile 257002094bc5935dd63207a380d9698ab81f0775 from your Git powerpc-dma.6-debug today.
Unfortunately I don't see any error messages (kernel ring buffer) and I don't have a RS232 serial null modem cable to get them.
Cheers, Christian _______________________________________________ iommu mailing list iommu@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/iommu
