Kernel 2.6.5 - Compaq Fibre Channel 64-bit/66Mhz HBA

[Bolke de Bruin <bdbruin@aub.nl>]

Hello,

The company I work for is investigating a switch from Windows 2000 to a 
Linux based setup for its databases. Because of a dependancy on a third 
party we need to settle on kernel 2.6.5. Although the database servers 
will be moved to x86_64, we would like stay using our raid array 
(StorageWorks 4100) as it has been quite a tremendous investment for the 
size of our company and it still works.

However it is unclear if the current controller "Compaq Fibre Channel 
64-bit/66Mhz HBA" is actually supported. This controller has been marked 
broken from kernel 2.6.7 and onwards with a "This is too much stack" 
(drivers/scsi/cpqfcTScontrol.c). Any additional documentation I cannot find.

So the basic question is. Does this controller work on kernel 2.6.5?

and if not and someone wants to give some advice, is it possible to 
replace the controller without having to move to a different raid array 
setup or is a fix pretty easy to create?

Kind regards and thanks in advance,
