NetBSD 5.0.1-RELEASE GENERIC kernel on i386.
>Description:
Hello. I have a Samsung NC10 netbook. According to 
http://netbsd.org/ports/i386/netbook.html its wireless is supported thanks to 
some Atheros patch, but I can't find it anywhere. Also 
http://wiki.netbsd.se/Samsung_NC10 shows thath everything is OK with the 
wireless card.

But a fresh 5.0.1 install show something like this:

ath0 at pci1 dev 0 function 0
ath0: interrupting at ioapic0 pin 16
ath0: unable to attach hardware; HAL status 13

On FreeBSD 8-RELEASE everything is OK, so is on Linux. Here are some additional 
Linux info:
02:00.0 Ethernet controller: Atheros Communications Inc. AR242x 802.11abg 
Wireless PCI Express Adapter (rev 01)
        Subsystem: Foxconn International, Inc. Device e00c
        Flags: bus master, fast devsel, latency 0, IRQ 16
        Memory at f0100000 (64-bit, non-prefetchable) [size=64K]
        Capabilities: [40] Power Management version 2
        Capabilities: [50] MSI: Enable- Count=1/1 Maskable- 64bit-

        Kernel driver in use: ath5k

and:

ath: EEPROM regdomain: 0x68
ath: EEPROM indicates we should expect a direct regpair map
ath: Country alpha2 being used: 00
ath: Regpair used: 0x68
ath5k phy0: Atheros AR2425 chip found (MAC: 0xe2, PHY: 0x70)




>How-To-Repeat:
Install NetBSD 5.0.1 or 5.0.2 RELEASE on a Samsung NC10 netbook.
>Fix:
Maybe porting some parts of FreeBSD's 8 ath driver will help.
