I'm announcing the release of the 2.6.31.1 kernel. All users of the
2.6.31 kernel series are very strongly encouraged to upgrade.
I'll also be replying to this message with a copy of the patch between
2.6.31 and 2.6.31.1
The updated 2.6.31.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-2.6.31.y.git
and can be browsed at the normal kernel.org git web browser:
http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.31.y.git;a=summary
thanks,
greg k-h

This is still broken for me. For years, I didn't have a broken
kernel. When I booted with 2.6.31, it never reached the login
prompt - http://marc.info/?l=linux-kernel&m=125340020804711&w=2
I'd appreciate if anyone can find anything missing in the
attached config. I'm also sending a diff from 2.6.30.7.
And

If some fields are empty or look unusual you may have an old version.

Looks like the following patch was missed:
http://patchwork.kernel.org/patch/48380/
and link to the thread where it was discussed:
http://lkml.org/lkml/2009/9/17/397
Please, add it to 2.6.31. Thanks.

Whilst technically still "polling a website" there's an RSS feed on
<http://www.kernel.org/> which I use happily with Google Reader. You do
get some 'noise' from the other releases (git snapshots, linux-next
releases).

linux-kernel-announce should work, perhaps something recently broke when
the backend kernel-org stuff was changed. Try pinging the kernel.org
admins about this.

It just didn't make it in time. It is now queued up for the next
