Hello.

We have a very stange problem with "LSILogic 1030 Ultra4 Adapter". There is an information about it:

mpt0: <LSILogic 1030 Ultra4 Adapter> port 0x4000-0x40ff mem 0xdc120000-0xdc13ffff,0xdc100000-0xdc11ffff irq 18 at device 3.0 on pci3
mpt0: [GIANT-LOCKED]
mpt0: MPI Version=1.2.14.0

Everything works fine, but time to time disk operations hangs and we have this messages in log:

mpt0: request 0xc4bd81f0:196 timed out for ccb 0xc4dedc00 (req->ccb 0xc4dedc00)
mpt0: attempting to abort req 0xc4bd81f0:196 function 0
mpt0: completing timedout/aborted req 0xc4bd81f0:196
mpt0: abort of req 0xc4bd81f0:0 completed

mpt0: mpt_cam_event: 0x0
mpt0: completing timedout/aborted req 0xc4bd8220:198
(da0:mpt0:0:0:0): lost device

(da0:mpt0:0:0:0): Synchronize cache failed, status == 0x4a, scsi status == 0x0
(da0:mpt0:0:0:0): removing device entry

SCSI-bus connected to Areca RAID-controller and this controller works fine with MS Windows.
