I'm trying to start ath0 and I keep getting "kernel panic - not syncing: ifmedia_set" on the console. I don't get any errors whatsoever in the logs to help debug this. Any ideas? Any recommendations on what I can set to turn on excessive messages until I get this figured out?

lspci -v:
02:07.0 Ethernet controller: Atheros Communications, Inc. AR5212 802.11abg NIC (rev 01)
Subsystem: D-Link System Inc D-Link AirPremier DWL-AG530 Wireless PCI Adapter
Flags: bus master, medium devsel, latency 168, IRQ 11
Memory at fde00000 (32-bit, non-prefetchable) [size=64K]
Capabilities: [44] Power Management version 2

SW Versions:
sys-kernel/gentoo-sources-2.6.16-r4
net-wireless/madwifi-ng-0.1502.20060414
net-wireless/madwifi-ng-tools-0.1502.20060414
net-wireless/wireless-tools-29_pre9

I had the same issue using gentoo-source-2.6.15-r1 and the released madwifi drivers. I've never been able to get this card to work. I'd like to set up an AP but I thought I'd follow the wiki to get it working but that failed miserably too.

I'm not trying to be a troll, but don't buy D-link hardware: problem solved.

They are subpar and have been known to screw people over. Please do not support D-link.

I guess noone else has seen this error? I can start ath0 once but if I stop it, then start it again, I get the kernel panic. As mentionned, there are no other messages on the console and there are no messages whatsoever in the messages file.

Good news, had the same problem when received signa S/N was
only 12dB. However, this bug seems to be solved already, look here:
