Check for a firmware update for your fujitsu drive.  We have
some firmware updates for fuji drives on our dload site and 
go thru support.dell.com and drill down and match your drive
and see if there is one.

Hi,

Well, I downgraded my kernel to 2.4.20-18.8 and installed the latest aic7xxx
driver (6.2.36). Everything seems to work, but I got this message upon
bootup:

blk: queue c181dc14, I/O limit 4095Mb (mask 0xffffffff)
(scsi0:A:0): 160.000MB/s transfers (80.000MHz DT, offset 127, 16bit)
scsi1:A:0:0: DV failed to configure device.  Please file a bug report
against this driver.
  Vendor: FUJITSU   Model: MAM3184MC         Rev: 5A01
  Type:   Direct-Access                      ANSI SCSI revision: 03

What does this mean? I believe 'DV' stands for Domain Validation, but that's
pretty much all I know. A bit of Googling shows me that this could possibly
be to-do with the firmware on the SCSI drive in question and that there are
settings for enabling/disabling Domain Validation in the Adaptec's
SCSI-Select BIOS.

I'm not quite sure where to go from here. Any suggestions? Do I have a bad
drive that is causing me all these problems?

Regards,

Basil Hussain
