9.1-rc1 mps timeout error

[Jason Keltz]

(somewhat) Related to my previous message....

I have a system which has an Intel S3000AH server board with an LSI 
9211-8i card  with SAS2008 chipset, running IT firmware.    It is 
connected to an older Chenbro CK12803 expander card which is connected 
to the 16 disk ports in an AIC RMC3E2-XPSS 3U chassis.  At this time, I 
have only 12 SATA disks in the system ( 1 x 1 TB, 11 x 2 TB). The disks 
are all recognized, although interestingly enough, all of them report 
ENC SLOT 0 on the 9211-8i bios display of disks.

At the end of the 9.1 boot sequence, I see:

mps0: mpssas_scsiio_timeout checking sc 0xffffff8000759000 cm

I'm wondering if this is something to be concerned about?

Output of "camcontrol devlist" is:

... I'm guessing the above error is talking to the Chenbro expander 
card. (mps0:0:19?)

At this point, I've been ignoring the error, but if I can add a bit 
somewhere to make it go away, it would be even better.

Thanks for any assistance..

Jason.
