Bugzilla Bug 185255

Hello,

There's a bug in mac80211 (included recently in the 2.6.22 kernel) that can
cause some bad deadlocks. In my case I found the problem in iwlwifi in
conjunction with wpa_supplicant.

There is already a patch in wireless-dev that should be included in the
mainline kernel, but before it does the patch can be included in the
gentoo-kernel patchset.

The relevant thread is here:
http://marc.info/?l=linux-wireless&m=118436322132249&w=2

The patch that fixes it is here:
http://marc.info/?l=linux-wireless&m=118309770324214&q=p5

Cheers,
  Renato

Thanks, will include in next release

Next version of vanilla's kernel will include this patch and other things
related to mac80211 too (packed injection, etc..).

I suggest waiting to kernel 2.6.23 to test, and never have 2.6.22 marked as
stable.

See http://www.kernel.org/pub/linux/kernel/v2.6/testing/ChangeLog-2.6.23-rc1

No. We will backport the fix and mark 2.6.22 stable in the usual timeframe.

Ok, any possibility to have the other mac80211 usefull patches besides this one
as well in next release?

bug fixes (which affect you): yes, file a bug
everything else: no

Fixed in gentoo-sources-2.6.22-r2 (genpatches-2.6.22-3)
