I have the same problem on a Compaq DL360 G1 with the imbedded SmartArray controller. It happens on both the 6.10 and the 6.06 alternate versions. I have tried default and complex installations of both. It installs fine, but when it reboots after the install it hangs at mounting the root file system. It looks like grub is treating the primary disk as an IDE disk instead of a SCSI disk.
