Thanks for your reply,

Here's what I did until now:

The machine is a HP DL320G5p Server with HP embedded SATA-RAID-controller.
This one is really shit. I already had huge problems with it before.

After the hard reset of the server, the problem I described above occurred. I 
tried to modifiy the grub-boot-parameters...without any success.

Next I made a backup of the boot partitions of the second machine, which should 
be exactly the same and restored it on the failing machine -> result was: 
booting from hard disk wasn't possible anymore. Only cryptic signs and a frozen 
machine...

After that I made a super-grub-floppy and started grub from that and told him 
exactly which kernel and which initrd from which disc to boot. I saw the 
boot-process again, but with failing on exactly the same place.

Next, I booted from the RHEL5-DVD and went into rescue mode. I tried to run 
fsck on /dev/sda1 but that wasn't possible for some reason, so I extracted the 
kernel from the rpms and copied it into /boot to make sure he is working. But 
also that failed.

So I will now try your advice. What steps are neccesary to check the filesystem 
on that device?

I'll boot into rescue mode and then I have 3 possibilities:
Skip
Readonly
Normal=readwrite?
Which possibility should I choose?
I always chose readwrite, but with this one fsck went wrong!
But I didn' chroot in. May that have been the failure?

OK, i'll even try this one. 

Thanks for any advice.

Time is running out :(
