eata module for DPT SCSI cards

Hi, I'm still having to have the following applied to be able to use the 
eata driver for my DPT2044W SCSI card.

Is there any chance that this could be mainlined or another fix 
implemented that can be mainlined?

As it is with the following patches applied, I still have to unload and 
reload the eata driver before mounting filesystems on the disk attached 
to the DPT2044W SCSI card that uses the eata driver, otherwise kexec 
reboots fail.

Without the patches applied, the machine locks up when it tries to load 
the eata module.

Arthur.
