A kernel bug report was opened against Ubuntu[0]. We performed a kernel
bisect, and found that a change introduced by upstream linux kernel
commit 786235eeb introduced the bug as of v3.13-rc1.

The bug indicates an issue with the SAS controller during
initialization, which prevents the system from booting.

There has been an on-going discussion on LKML[1] regarding this issue.
It was found that this bug can be avoiding by increasing systemd-udevd's
30 seconds timeout.

We were hoping to get some feedback from the systemd maintainers to see
if it possible to increase the timeout to 120 seconds, or if there would
be any possible complications with doing that?
