Still my question is not cleared,  firmware crash is due to this patch ? Also let me know do you observed same behavior with any other chipset ?

there is not much  traffic required. as it seems the firmware crashes immediatly after association. the issue is also not present in 10.4-3.4-0082ww

> Can you share the more details on firmware crash ?

so a firmware crashdump from log? i'll try to get it within the next hours. just need to resetup the test scenario
