Yes, indeed. Set RID function did not survive CmdCompl changes without problems. There was a horrible bug in it that caused deadlocks when any other command (e.g., transmit for TX packet) was pending. Set RID called hfa384x_cmd() (that can sleep after the CmdCompl changes) while holding a spinlock and with interrupts disabled.. This is now fixed in CVS.
