[Bug 111123] i2o DPT RAID driver broken. Known bug in 2.6.20. Patch available.

[Nick_Hill]

Public bug reported:

Binary package hint: linux-image-2.6-686

1)Install Feisty and updates.
2)Install Adaptec or other DPT based SCSI RAID controller.
3)Create RAID drive in BIOS
4)Boot system
5)Check dmesg | grep i2o
or do 
fdisk /dev/i2o/hda
>Unable to read /dev/i2o/hda
dmesg | tail

You will see:
[  537.586625] Buffer I/O error on device i2o/hda, logical block 0
[  537.586632] Buffer I/O error on device i2o/hda, logical block 1
[  537.586635] Buffer I/O error on device i2o/hda, logical block 2
[  537.586637] Buffer I/O error on device i2o/hda, logical block 3

This is identical to the bug, and the patch shown at:
http://www.mail-archive.com/linux-kernel@vger.kernel.org/msg136638.html

I2o RAID arrays and other DPT based controllers are unusable with
Feisty.

Apparently, this bug has been patched in official kernel 2.6.21. Can we
have the next Feisty kernel update patched with a fix for I2o please?
This is a complete stopper for many systems.
