Subject: Re: linux-4.5-rc1 TI pandboard-es wifi wlcore locks and reset

Just updated to the latest linux-4.5-rc2 and same result as rc1.

The wireless module loads firmware and then stalls causing a reset of
the device and then continues to go through a stall and reset cycle.

please find enclosed a copy of the dmesg output.

Is there anyone else testing a pandaboard with linux-4.5-rc2?

Just for completeness also tested the latest linux-4.4.1 kernel and
found no problems with the wireless modules.

Regards,

Ross Green
