Instead of booting into the running system this machine stops and on the terminal I can see a message:

could not stat resume device file /dev/sdb5 

When I attach a keyboard and press enter the boot continues and the machine comes up like normal.

But it's essential that this machine comes up under most circumstancs alone.

There never was something like a "resume" on this machine.

I tried several times to reboot, but this does not happen on all boots, I can not find a pattern here.

There is a software raid running on the box.

This is the syslog during boot:

How can I get rid of this boot failure? We do not need resumes and best would be something that works here and now.
