Title:
Raring update to 3.8.13.5 stable release
Status in “linux” package in Ubuntu:
Confirmed
Status in “linux” source package in Raring:
Fix Released
Bug description:
SRU Justification
Impact:
The upstream process for stable tree updates is quite similar
in scope to the Ubuntu SRU process, e.g., each patch has to
demonstrably fix a bug, and each patch is vetted by upstream
by originating either directly from Linus' tree or in a minimally
backported form of that patch. The 3.8.13.5 upstream stable
patch set is now available. It should be included in the Ubuntu
kernel as well.
git://kernel.ubuntu.com/ubuntu/linux.git
