Kernel does not detect third hdd on cold boot

Binary package hint: linux-source-2.6.20

Hi there,

On my PC I have three hard disks:
IDE disk Maxtor 6Y060L0, with grub, /boot/ and other OS partitions, detected as hda.
SATA disk ATA SAMSUNG SP1614C with / and swap partitions, detected as sda.
SATA disk ATA WDC WD1200BEVS-7 with one large NTFS partition, detected only on reboot as sdb.

When I turn the computer on, kernel detects only two disks, hda and sda.
When I re-boot (warm boot), all three disks are detected and everything is Ok.
The other OS detects all disks on cold boot, so I think its not a hardware problem.

Upgraded to feisty, kernel 2.6.22-14-generic #1 SMP has same problem.

The Hardy Heron Alpha series is currently under development and contains an updated version of the kernel. You can download and try the new Hardy Heron Alpha release from http://cdimage.ubuntu.com/releases/hardy/ . You should be able to test the new kernel using the LiveCD. If you can, please verify if this bug still exists or not and report back your results. General information regarding the release can also be found here: http://www.ubuntu.com/testing/ . Thanks.

The disk in question died yesterday. Seems like there was the hardware problem, so I'm closing this bug as invalid.
