Comment 84 for bug 290153

Upgraded a Dell SC1425 from hardy to intrepid. Controller: Adaptec ASC-39320(B), module: aic79xx

linux-image-2.6.27-7-generic drops to in the intitramfs, waiting a bit and running exit allows the startup to continue.

linux-image-2.6.24-19-generic booted fine.

[ 3.370368] e1000: eth1: e1000_probe: Intel(R) PRO/1000 Network Connection
[ 18.052543] scsi0 : Adaptec AIC79XX PCI-X SCSI HBA DRIVER, Rev 3.0
[ 18.052545] <Adaptec (Dell OEM) 39320 Ultra320 SCSI adapter>
[ 18.052547] aic7902: Ultra320 Wide Channel A, SCSI Id=7, PCI-X 101-133Mhz, 512 SCBs

You can see from the timestamps it takes a little while for the disk to show up.

Installed linux-image-2.6.27-10-generic from proposed ( https://wiki.ubuntu.com/Testing/EnableProposed )

Same issue.

added rootdelay=90 to kopt line in /boot/grub/menu.lst, ran update-grub, reboot, system boots fine.
