NetBSD 6.1.4 NetBSD 6.1.4 (GENERIC) i386
Kernel hangs when a connection is made to a wireless Atheros card.  When hung, the kernel won't respond to a Control-Alt-ESC.  Running top up to the point of the hang seems to indicate the kernel is not running out of dynamic memory.  Two Atheros cards have been tested with the same results.  One responds with a Vendor/Device code of 0168c/0023 (AR5416) and the second responds with a Vendor/Device code of 0168c/0029 (AR9280).
