That's a huge amount of data. Can you show cat /proc/scsi/scsi of the machine
(as well as the lspci etc)?

Does RAID-5 mean you have a storage array attached? i.e. IBM 3542, fastt 200?

It looks like the latest qlogic qla driver includes 2.5.x support,
I haven't tried it but will at some time:

Luns 0-31 look like this:

Host: scsi3 Channel: 00 Id: 01 Lun: 00
  Vendor: IBM      Model: 3542             Rev: 0401
  Type:   Direct-Access                    ANSI SCSI revision: 03

Luns 32-127 look like this:

Host: scsi3 Channel: 00 Id: 01 Lun: 32
  Vendor: m  m  m  Model: m  m  m m  m  m  Rev:
  Type:   Direct-Access                    ANSI SCSI revision: ffffffff

Luns 32-127 shouldn't be accessible from this machine.
I believe it's part of a SAN at OSDL.

Yes, hardware raid5.  It appears to the OS as /dev/sdc.

Thanks.  The new driver appears to have 2.5 bits similar to
Lincoln Dale's patch for v6.1b2.
