Vanilla iso, no installer updates. Boot from cd-rom - detects 2940U2W & disk as sda - second disk on INI-9100UW as sdb. After installation boot fails to load root - driver modules are now loaded INI-9100 before AIC-7xxx (thus swapping the disks). /etc/modules.conf reads alias scsi_hostadapter aic7xxx alias scsi_hostadapter1 initio I changed this to read alias scsi_hostadapter0 aic7xxx alias scsi_hostadapter1 initio and recreated the initrd image. It now loads the AIC-7xxx driver first.
This is fixed in the mkinitrd in Raw Hide. If you'd like to work around it, change the calls to sort in mkinitrd from: sort -u to LC_ALL=C sort -u (the en_US locale is broken...)
