Comment 4 for bug 2015827

Judging from the utter lack of response to the core issue of backporting untested patches from an - at the time - release candidate unstable upstream Linux version, back to what is supposed to be *three* long term support "enterprise grade" Ubuntu editions, it seems that Ubuntu's policy for Linux kernels has gone to "move fast and break things".

Basically, for stability with Ubuntu, there is now only one option:

Roll your own Linux LTS kernels.

This experience has completely undermined my trust in Ubuntu as a stable platform for servers.
