Multiple SATA disks, two OSs and booting problem

[Tero Mäntyvaara <termant@gmail.com>]

Hi,

I have got motherboard that has support for four (4) SATA devices. 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 (SATA) disks. Everything works well.

But if I connect two other disks (SATA2), there is volume group (named 
VG1) on those disks and KnoppMyth OS installed on one partition of the 
other disk, booting into Debian fails.

Further investigated: If I connect either of the two KnoppMyth VG1 disks 
Debian boots well.

And while all disks connected booting into KnoppMyth goes well.

Here is the output:
kinit: name_to_dev_t(/dev/mapper/VG0-LV--swap) = dm-8(253,8)
kinit: trying to resume from /dev/mapper/VG0-LV--swap
