I: Problerm with the installation of RH6.0

["Luca Dentella" <lucad spm it>]

 Hello!
  I downloaded the ISO image of the RedHat 6.0 CD and I burned it.
 The CD is bootable: I inserted it in my CDROM and the installation started.
 I chose "expert" ('cause I had problems...), italian keyboard, installation
  from the CDROM and I chose my SCSI card (Adaptec AHA2940U2W with 2.11.0
 firmware). Then I saw the program scanning my devices, founding:

 id0 IBM SCSI Ultra/2 HD
 id1 IBM SCSI Fast HD
 id2 IBM MagnetoOptical Drive
 id3 YAMAHA 4260 CD Recorder
 id4 PIONEER 36x CD-ROM

 At this point I received a lot of these error messages:
 <4> scsi : aborting command due to timeout: pid 45, scsi 0, channel 0, id
5,
 lun 0
 test unit ready 00 00 00 00 00

 If I hit CTRL-C I get a "Kernel Panic" message and the PC hangs... I tried
 to let my PC work for an hour but nothing changed: I saw a lot of the
 messages as above.

 I have on my PC a RedHat 5.2, installed with the same configuration as now
 (same SCSI card, same devices) and I hadn't any problems installing it.
 Which is the problem now??? How can I solve?
 TNX!
