  *** NetBSD: It'll be there when you're ready for it. ***
System: NetBSD 4.99.52 NetBSD 4.99.52 (TPX61-1.28) #23: 
Wed Feb 6 22:53:00 JST 2008
Architecture: i386
Machine: i386

My Lenovo 802.11a/b/g wireless MINI-PCI Express adotper (PN 40Y7028)
is configured as ath and ifconfig reports correct MAC address etc.
But when invoke "ifconfig ath0 up" kernel reports 

'ath0: ath_chan_set: unable to reset channel 8 (2447 MHz, flags 0x3e0 hal flags 

and no wireless connection established. Also, "ifconfig ath0 down up" produce

'ath0: unable to reset hardware; hal status 0'

kernel message. 
Both messages are described in ath(4) as "This should not happen."

Simple google search leads the chip is Atheros AR5006EX but I don't know
that is correct or not.  Here is pcictl output .
