Adaptec 2100s & Debian stable

[Fabrizio Pedersoli]

Hi all guys!
i have a big problem with an Adaptec 2100s scsi controller, which manages 2
disks in RAID-0. the Debian installer found correctly that raid and the
installation process terminates fine. But when i reboot, after linux loads
i20 modules and founds hdd... it stops saying "waiting for root filesystem".
any suggestions??? thanks (and sorry for my english :D).
