I recently installed a Pre-migration NetWare 6.5 SP6 server onto an IBM
x3500 server and the boot process is hanging for a few minutes when it tries
to load the AACRAID.HAM driver and then subsequently gets to "Scanning for
Devices and Partitions".

It eventually does mount the SYS volume and finish booting, but I am
concerned about the long delay at this stage in the boot process. Has
anybody else experienced this issue? I've never seen any previous NetWare
installs take this long.
