mpt problem

[Vladimir Melnik]

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)

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