2.6.13.2 aacraid regression

[Juan D Ch <jchimienti@most.com.ar>]

Hi this is my first post in the list. I will try to make this mail short 
and useful, sorry but english is not my first language.

I have a client that has a HP Proliant ML 150 G2 with a 6 port SATA RAID
Controler Adaptec 2610SA, with HP part number 372953-B21. 
I tried to install debian, but 2.6.8 kernel doesn't support this controler.
So I installed the system in a PATA drive and then compiled the 2.6.13.2 
kernel from kernel.org. This kernel recognizes the controler so i formatted 
the array and start coping data. I copied some  dirs in /dev/sda1 
and then, after transferring a random amount of data (sometimes a couple
of MB, sometimes a few GB) the following messages appear:

------

Sep 30 10:16:59 syrah kernel: aacraid: Host adapter reset request. SCSI 
hang ?
Sep 30 10:16:59 syrah kernel: aacraid: Host adapter appears dead
Sep 30 10:16:59 syrah kernel: scsi: Device offlined - not ready after error 
recovery: host 0 channel 0 id 0 lun 0
Sep 30 10:16:59 syrah last message repeated 2 times
Sep 30 10:16:59 syrah kernel: SCSI error : <0 0 0 0> return code = 0x6000000
Sep 30 10:16:59 syrah kernel: end_request: I/O error, dev sda, sector 895
Sep 30 10:16:59 syrah kernel: scsi0 (0:0): rejecting I/O to offline device

-----

When this happens, I need to reboot in order to see the device again.

I tried 2.6.12.6 with the same options and the controller works fine.

As this is a production server it's difficult for me to track down the
exact change that introduced this error; so any hints would be highly
appreciated.

Thanks a lot
