[Bug 587437] [NEW] Boot very slow in AHCI bios controller mode

[PaoloVIP]

Public bug reported:

On netbook Toshiba NB200 with Lucid Lynx - 2.6.32-22-generic-pae #33-Ubuntu SMP
If in bios the controller mode is setting to AHCI the boot will take a very long time to end the process. Changing the bios controller mode to "compatible" the boot will carry on normally.

Part of dmesg in AHCI mode:

[    1.641676] sd 2:0:0:0: [sda] Attached SCSI disk
[    7.966049] EXT4-fs (sda1): mounted filesystem with ordered data mode
[  427.658441] udev: starting version 151

Part of dmesg in compatible mode:

[    0.862222]  sda: sda1 sda2
[    0.888906] sd 2:0:0:0: [sda] Attached SCSI disk
[    0.888941] Freeing unused kernel memory: 672k freed
