RocketRAID, SATA disks and booting problem

[Tero Mäntyvaara <termant@gmail.com>]

Hi,

I have installed Debian 4.0r2 AMD64 on filesystem witch has been build 
on top of LVM system. LVM is on top of software-raid1 device md0 with 
two SAMSUNG SP1614C disks. Disks are connected to RocketRAID 1640 
SATA-controller. Everything works well.

But if I connect two other disks to controller that is on the 
motherboard, there is LVM VG1 on these disks and KnoppMyth OS installed 
on one partition of the other disk, booting into Debian fails. I have 
choosen to boot from RocketRAID. If I swap the disks on RockerRAID to 
the motherboard controller and disks on motherboard conroller to the 
RocketRAID there is no difference.

Here is the illustration of the disks:
