1) cleanup ioc_reset callback handlers, introducing wrappers for synronizing
error recovery (mpt_set_taskmgmt_in_progress_flag,
mpt_clear_taskmgmt_in_progress_flag), as the fusion firmware only handles one
task management request at a time.
2) set vtarget->deleted flag when devices have been removed.
3) [EMAIL PROTECTED] - fix's provided from SGI after testing with single
threaded internal commands
