Bug Description
My bootstrap based on ubuntu lts-trusty.
Bootstrap often failed to startup on lenovo RD640 server, kernel complains about stucking for too long.
The log indicates system-udevd has lots of timeout events.
This bootstrap works fine with other DELL and INSPUR servers, and is only fails on the peculiar Lenovo ThinkerServer RD640.
[Steps to reproduce]
reboot a few times, occasionally it will fail
[Expected result]
boot normally and success
[Actual result]
boot failed and enter into systemd emergency shell
[Workaround]
I have tried adjust system-udevd timeout time, but it does not work.
One thing I notice is that my monitor print very slow, so I figure out it is related with kernel debug. The output of debug keeps cpu too busy, it does not has time to execute system-udevd commands.
I have tried delete "debug" kernel boot parameter and it works.

So the the problems is whether it is necessary to keep it. In what circumstance we need it.
