We (the -stable team) are announcing the release of the 2.6.29.1 kernel.
There's many bugfixes all over the tree, but this should specifically
fix the networking issues people had w/ 2.6.29. As usual, you're
encouraged to upgrade. For details see the changelog and diffstat
below.
I'll be replying to this message with a copy of the patch between
2.6.29 and 2.6.29.1.
The updated 2.6.26.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-2.6.29.y.git
and can be browsed at the normal kernel.org git web browser:
http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.29.y.git;a=summary
thanks,
