I finally got vinum to work, it turned out to be a bad hard disk. However,
once I took the bad disk offline, another disk begins to acted up. Here is
the diagram of the scsi chain.

cindy.fynet.com                                  fanying.fynet.com
                [T]                          [T]
               /                                \
[AHA 2940UW]===                                  ===[AHA 2940UW]
               \                                /
                --[WDE9100 (0)]--[WDE9100 (1)]--

The disk that is now acting up is WDE9100(1) and it is giving the error
message below. I am wondering why is FreeBSD keep on hiccuping whereas
Linux doesn't complain at all?
