Bug#434601: kernel -switching scsi devices on boot, unable to automount on startup

["Mgr. Peter Tuharsky" <tuharsky@misbb.sk>]

Package: kernel-image-2.6-686-smp
Version: 2.6.18+6

I have dual Opteron server based on TYAN S2882-D Thunder K8SD Pro 
mainboard. Disks are IDE, SATA, SATA, SCSI RAID 5 on Adaptec 2130S PCI-X 
controller.


When booting standard kernel, I cannot have SATA and SCSI disks mounted 
automatically from fstab. Seems, that in the middle of booting process, 
the SCSI disks simply switch their positions.

First the SATA takes sda+sdb and SCSI takes sdc until the time of fsck. 
Then, upon mounting, SATA takes sdb+sdc and SCSI moves to sda.

As the disks have different partitioning, I get either fsck errors or 
mount errors, whatever I set the fstab.

The only way is to disable automatic mounting and perform the mound 
manually after the whole bootup process.


If I use custom compiled all-in-one kernel (without modules), everything 
keeps stable: SCSI takes sda, SATA takes sdb+sdc, definitely.


I attach kernel log files from Debian (2.6.18) and from custom 
(2.6.19.2) kernel.
