Slow detection of Dell SAS 6i/R aka LSILogic SAS/SATA Adapter (mpt0)

Hi,

I'm not sure if I should have sent this to freebsd-questions@, but 
here we go.

I have a couple of Dell PowerEdge R200 rack servers, both equipped 
with the Dell SAS 6i/R RAID controller, running i386 7.2-RELEASE but 
they'll soon be upgraded to i386 7.2-STABLE.

The mpt driver spends a minute or so eager to initialize the 
controller, but fails with the following messages:

mpt0: <LSILogic SAS/SATA Adapter> port 0xec00-0xecff mem 0xdfbec000-0xdfbeffff,0xdfbf0000-0xdfbfffff irq 16 at device 0.0 on pci1
mpt0: [ITHREAD]
mpt0: MPI Version=1.5.18.0
mpt0: mpt_wait_req(6) timed out
mpt0: port 0 enable timed out
mpt0: failed to enable port 0
mpt0: unable to initialize IOC

The virtual disk comprised of two SAS disks is recognized as the 
following:

da0 at mpt0 bus 0 target 0 lun 0
da0: <Dell VIRTUAL DISK 1028> Fixed Direct Access SCSI-5 device 
da0: 300.000MB/s transfers
da0: Command Queueing Enabled
da0: 285568MB (584843264 512 byte sectors: 255H 63S/T 36404C)

Is there a way to get rid of the slow and failing initialization?
I'd be happy to try out patches or even allow shell access.

Complete dmesg output is available on demand. I can arrange for a 
verbose dmesg output if verbose booting is still an option. I can't 
remember the last time I attempted a verbose (re)boot.


Trond.
