Hi Everyone!
I will answer my own question, because I have solved the problem.
It turned out to be because of "VT-d" option enabled in BIOS. Probably
the
stock debian kernel and other distros I have mentioned have passthrough
options enabled, thus
the RAID card was given to XEN for usage somehow. With disabling the
option, everything started to work flawlessly.
There is probably a method to disable the passthrough of the RAID-card only
and you don''t need to disable VT-d globaly, but for me this is a
solution
for now. There are also servers that do not have VT-d option in
their BIOS, so maybe there another solution will be needed (kernel
recompile without passthrough options).
BTW I have also tried acpi=off which made me able to boot in some
situations, but xend did not want to start, so I took the option out. I
have read somewhere that this is also a solution sometimes to similar
problems, but not for mine I guess. VT-d disable worked like a charm!
Bye,
Daniel
