I tried but now i disabled to avoid a mixup of to many issues.

Last time it happened as creating filesystems, perhaps it's something
about disk usage. At the end of the mail i describe more about the disk
problems.

It happens or not, it's randomly.

If it's freezing then i cannot do anything, i can connect with iamt and
reboot, nothing else.

Sure.

Whats that parameter for?
I switched the disk because there was an error on the last one, now on
sata2 there is a brand new disk and i can see following on my console
log. I cannot believe it's a disk problem, perhaps it's a disk
controller problem instead or there is something with the kernel. I will
add the parameters and switch off/on the machine to restart from scratch.
