Public bug reported:
Ubuntu server now uses the '-generic' kernel, as the '-server' kernel
doesn't exist anymore. With this change the default server disk
scheduler changed from deadline to CFQ. This is very bad for servers,
deadline should absolutely be the default for servers.
For example we moved some KVM images to an Ubuntu 12.04 server, but we
had to revert as we got lots of disk errors and eventually frozen disks
on these KVM's due to write timeouts. It took us a while before we found
out that this 12.04 server used CFQ, which surprised us a lot.
