rootdelay the Linux boot

Just now I had with a brand new Linux installation, a problem the first time the new system. The error was not initially apparent, after a long debugging has shown the error as follows:

During the transition from initrd to the kernel and mounting the filesystem Grub reported the following error:

ALERT! /dev/sda2 does not exist. Dropping to a shell!

Then I was greeted by one of the BusyBox shell I unfortunately did not continue.

Problem was simply the loading of the SAS Controller Module (mptsas) takes the system far too long to find the plates and aborts with a timeout.

The error can be explained by the parameter

rootdelay=45

fix in the kernel command line.
