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:
> options MSGBUFSIZE=98304
> options DIAGNOSTIC # expensive kernel consistency checks
> options DEBUG # expensive debugging checks/support
> options LOCKDEBUG # expensive locking checks/support
< file-system LFS # log-structured file system
> #file-system LFS # log-structured file system
> options ACPIVERBOSE # verbose ACPI configuration messages
> options PCIVERBOSE # verbose PCI device autoconfig messages
> options PCI_CONFIG_DUMP # verbosely dump PCI config space
> options PCI_INTR_FIXUP # PCI interrupt routing via ACPI
> options PCI_ADDR_FIXUP # fixup PCI I/O addresses
> # Huawei E220 3G/HSDPA modem
> uhmodem* at uhub? port ? configuration ? interface ?
> ucom* at uhmodem? portno ?

As recommended by NetBSD Developer jakllsch, upgraded laptop bios from
2.83 to 3.13 (latest), with no change relative to the mentioned bug.

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?
