l-b-m cfg80211 can't handle EU regdomain (Oops)

[Stefano Rivera]

The l-b-m ath9k works out of the box, but if I set pass the option ieee80211_regdom="EU" to lbm_cw_cfg80211 then I get a kernel oops.

Versions:
ii linux-image-2.6.28-7-generic 2.6.28-7.20 Linux kernel image for version 2.6.28 on x86/x86_64
ii linux-backports-modules-2.6.28-7-generi 2.6.28-7.5 Ubuntu supplied Linux modules for version 2.6.28 on x86/x86_64

Hardware:
MacBook 2.1:
02:00.0 Network controller: Atheros Communications Inc. AR5008 Wireless Network Adapter (rev 01)
 Subsystem: Apple Computer Inc. Device 0087
 Flags: bus master, fast devsel, latency 0, IRQ 17
 Memory at b0100000 (64-bit, non-prefetchable) [size=64K]
 Capabilities: <access denied>
 Kernel driver in use: ath9k
 Kernel modules: ath9k

Seems the problem is only caused when I set the regdomain to EU.

Just also want to point out bug 337929. Same issue, just using the ath5k driver and seeing a different stack trace for the oops. I suspect these are likely duplicates. Thanks.

This is very likely the same underlying issue as bug 337929, I will be working on both of these over there. We can mark this as a duplicate should the same fix both. You will want to subscribe to that other bug for updates.

Debugging this we found that there is bug relating to new support for the passive beacon scanning. This bug is no longer reproducible with the latest LBM wireless update. Moving Fix Committed, this package should release shortly after beta.

This bug was fixed in the package linux-backports-modules-2.6.28 - 2.6.28-11.12
