You have to be extremely precise while describing the situation because
there are missing pieces in the above stanza and the whole steps you
followed :-)
Okay, let's start over.
You installed the lsi card in one of the motherboard slots, configured
the BIOS to use a JBOD disk layout and then boot the installation CD for
Squeeze, right?
The installation proccess was smoothly (you selected a mdadm
configuration for the disks and then formatted them with no problems),
when the installer finished and the system first rebooted, you selected
the new installed system from GRUB2's menu and then, the booting proccess
halted displaying the mentioned messages in the screen, right?

So you think the system stalls because of the raid card despite you get
the same output messages at boot and there's no additional evidence of a
problem related to the hard disks or the controller.
Mmm... weird it is, my young padawan :-) that's for sure but it can be
something coming from your Supermicro motherboard's BIOS and the raid
controller. Check if there's a BIOS update for your motherboard (but just
check, don't install!) and if so, ask Supermicro technical support about
the exact problems it corrects and tell them you are using a LSI raid
card and you're having problems to boot your system from it.

Yes, I agree. It seems an unrelated problem that you can try to solve
once you correct the booting issue if the error still persists.

Ah, that's a very interesting discovery, man. To me it can mean the
motherboard is not correctly detecting the card, hence a BIOS issue.

I would center first in solving the core of the problem.

Are you reaching the GRUB2 menu? If yes, you can select "recovery mode/
single-user mode".
