I've suggested a couple of times already to run of FAST_MBUS, but others did not like the idea. And TBH they have a point, your board is the only one which has stability issues which seem to be caused by FAST_MBUS. Can you please work with Siarhei Siamashka to properly root cause this ? If it really is FAST_MBUS I'm all for disabling it,' but first lets make sure. Regards, Hans -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
