NetBSD goldstein.gardenali.biz 5.99.11 NetBSD 5.99.11 (GENERIC) #0: Mon Apr 27 02:12:40 BRT 2009  root@goldstein.gardenali.biz:/root/obj/sys/arch/amd64/compile/GENERIC amd64
>Description:
- Boot GENERIC normally: pci2 disabled
- Boot GENERIC -2: pci2 enabled; ath(4) crashes kernel
- Boot GENERIC -12: pci2 enabled; ath(4) enabled; keyboard disabled

Built special kernel FIXUPS (differences below), to better interpret the problems, and try some PCI fixups.

dmesg for normal boot and for noacpi nosmp boot are available on
http://evaldo.gardenali.biz/NetBSD-5.99.11-amd64/

As asked by people in freenode #NetBSD, yes, all the hardware in question work fine on Linux i386 and x86_64, and Windows Vista i386.
>How-To-Repeat:
My special FIXUPS kernel to try to debug the problem differs from GENERIC this way:

 How does ath(4) crash the kernel?  Can you send a stack trace?

 As for pci2 disabled, perhaps it was a temporary regression.  Try again?
