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? > > > Which of the mpt(4) clutter remains if you don't boot verbose? > > I can't kldunload module (kldunload wait on 'simfree'). > Reboot allowed. 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. > > mpt show only next: > > mpt0: <LSILogic SAS/SATA Adapter> port 0x1000-0x10ff mem 0xb1a40000-0xb1a43fff,0xb1a00000-0xb1a3ffff irq 16 at device 0.0 on pci15 > mpt0: MPI Version=1.5.20.0 > mpt0: Capabilities: ( RAID-0 RAID-1E RAID-1 ) > mpt0: 0 Active Volumes (2 Max) > mpt0: 0 Hidden Drive Members (14 Max) > ses0 at mpt0 bus 0 scbus7 target 8 lun 0 > ses0: <ESG-SHV.

Do you have any problems using the disks? Marius
