Description Frank Mayhar 2013-01-05 23:10:00 UTC 
	I'm trying to set up a new laptop, which has an Intel Centrino
	Ultimate-N 6300 wireless card.  I was under the impression that the
	9-stable iwn driver fully supported this card but I've run into a
	firmware crash:

        iwn0: iwn_intr: fatal firmware error
        firmware error log:
          error type      = "SYSASSERT" (0x00000005)
          program counter = 0x00003C2C

          tx ring 18: qid=18 cur=0   queued=0  
          tx ring 19: qid=19 cur=0   queued=0  
          rx ring: cur=7

	This crash happens when configured to use both 11a and 11g (or
	11na and 11ng).  It has blocked me from using this card with
	9-stable.

	Relevant bits from a verbose dmesg are:

I see the same firmware crash on 10.0-CURRENT r253805M.
Worked around by "ifconfig wlan0 -ht"
