strange boot problems

Hi,

I've noticed rare boot problems occurring on nodes installed via autoyast.

Some machines of our HPC cluster, currently containing around 60 nodes, 
sometimes

to not reboor correctly. So if the system crash OR I just enter "reboot" 
the system will not start again.

Grub i working the boot process is starting and then the system remains 
in a waiting state after 8 sec (see boot5.jpg).

The hard disk controller is loaded, the file system is clean - I have no 
idea what is blocking the system.

For the normal nodes a reinstall using autoyast was the fastest 
solution. But maybe someone has

an idea where to look for the problem ...

I haven't noticed this behavior on nodes installed manually...
