I'm using kernel 3.14.0-rc4-12738-g674748b-dirty on a am335x-evmsk as also on a custom board. I get following issue on both systems, when working with various calibrator functions: # calibrator wlan0 plt power_mode on [ 252.935208] wlcore: power up [ 253.502531] wlcore: firmware booted in PLT mode PLT_ON (PLT 6.3.10.0.133) # [ 399.656192] wlcore: ERROR Tx stuck (in FW) for 5000 ms.
