| |
From: Milan Kupcevic <milan@physics.harvard.edu>
Fix Promise SATAII 150 TX4 (PDC40518) and Promise SATA 300 TX4 (PDC40718-GP) wrong port enumeration order that makes it (nearly) impossible to deal with boot problems using two or more drives.
Signed-off-by: Milan Kupcevic <milan@physics.harvard.edu> ---
The current kernel driver assumes:
port 1 - scsi3 port 2 - scsi1 port 3 - scsi0 port 4 - scsi2
Having 4 hard drives connected to the controller grub recognizes the port 1 connected drive as "(hd0)" but kernel recognizes the port 3 connected drive as scsi0:0:0:0 (/dev/sda). There is no clean way to make it boot correctly.
