I started looking at this issue and managed to reproduce the issue instantly with dd if=/sys/firmware/acpi/tables/data/BERT of=/dev/null bs=7 I've attempted a few ways of fixing it based on the comments on this thread but wasn't successful so far (my knowledge is pretty limited in this area too, so not a big surprise). How can I be of assistance to debug/test patches for this issue? -- Aristeu _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
