Comment 8 for bug 569645

Same issue here.
It wouldn't be a problem if sdX naming convention was fully abandonned. Unfortunatly, many tools keep on using/showing sdX.
Is there a way to lock/stick a UUID to a sdX or to remove all sdX use/display in the system?
These random changes are confusing and puzzeling.
My boot drive is a PATA (/ /tmp) I want always sda. The second drive (/var /home /srv /swap) is a SATA attached to a PCI VIA VT6421
The issue began with the upgrade from KK to LL
Then I found that my 2 drives were swapped (The PATA was always sdb beginning with LL).
A disk dump shows that grub is in the MBR of the PATA and nowhere else.
I have the bios boot sequence set to HDD-0/disabled/disabled/disabled
Later I found that when enabling HDD prefetch mode in the bios (what is anyway a better setting), the random behaviour began. I can't figure if trying to manually set the IRQ's against PCI slots would help. I have no other bios settings that I can imagine related.
I found a file that shown (at a time the drives were swapped the wrong way - sorry I can't attach no more as the link is now broken)
