Dropped the portion of the diff with references to sa.c. Attached is the patch I feel will address this interrupt issue. As an added 'perk' I have also added the code to detect if the controller was previously initialized for interrupted operations by ANY operating system should the reset_devices kernel parameter not be set and we are dealing with a naïve kexec without the addition of this kernel parameter. The reset handler is also improved. Related to reset operations, but not pertinent specifically to this issue, I have also altered the handling somewhat so that we reset the adapter if we feel it is taking too long (three minutes) to start up. ObligatoryDisclaimer: Please accept my condolences regarding Outlook's handling of patches. This attached patch is against current scsi-misc-2.6 MINUS the initial version of this patch and the first patch that sets the missing platform function related to this discussion.
