Hi,

I am trying to compile kernel 2.6.9-11.EL from kernel-sourcecode, and need the Compaq cpqfc HBA driver. I see the code for the driver under drivers/scsi but when I do a "make menuconfig" I do not have the option to select it. Any ideas on how I can get it to show up?

If you look in drivers/scsi/Kconfig it states:

# This is marked broken because it uses over 4kB of stack in # just two routines: # 2076 CpqTsProcessIMQEntry # 2052 PeekIMQEntry # config SCSI_CPQFCTS tristate "Compaq Fibre Channel 64-bit/66Mhz HBA support" depends on PCI && SCSI && BROKEN help Say Y here to compile in support for the Compaq StorageWorks Fibre Channel 64-bit/66Mhz Host Bus Adapter.

You have to unselect 'Select only drivers expected to compile cleanly' in the 'Code maturity level options' to see this driver.

I assume it's marked as broken for a very good reason, so you may not want to do this ...

RedHat/CentOS disable 8K stacks completely in these kernels, so you might want to use a vanilla 2.6.X kernel with 8K stacks instead.
