Bug Description

On PXE installation of the latest Ubuntu 11.10 on a Dell R410 with a PERC H700 RAID card the disks are recognised by the megaraid_sas driver. However this appears not to happen fast enough for the disk-detect script and so the automated install is stopped asking which storage driver to use because no storage is found.

Because the storage has been found selecting any driver will work and install continues and finishes successfully.

Having had a look at the disk-detect script it would appear since there is already a sleep loop in there all that would need to changed to fix this bug is to increase the sleep timeout or number of loops in disk-detect.
