Hrm, could you please change the SAS1078 part in mpt_hard_reset() of
mpt.c to look like the following, i.e. add the printf()'s:
        if (mpt->is_1078) {
                printf("%s: reg before=0x%x\n", __func__,
                     mpt_read(mpt, MPT_OFFSET_RESET_1078));
                mpt_write(mpt, MPT_OFFSET_RESET_1078, 0x07);
                DELAY(1000);
                printf("%s: reg after=0x%x\n", __func__,
                     mpt_read(mpt, MPT_OFFSET_RESET_1078));
                return;
        }

and report the values printed during attach of mpt(4) with the above
compiled in?

Unloading of HBA drivers unfortunately still isn't really supported in
FreeBSD. The closest thing to working is isp(4), but even that one
doesn't successfully unload 100% of the time.

Okay, so apart from the lengthy delay during attach it looks good so
far. Do you have any problems using the disks?
