This output likely rules out your cabling and possibly your power supply
as being an issue.  All the link rates negotiated at 6Gbit and there are
no error, sync, or reset issues reported presumably by the hba which is
good.

I've seen issues similar to your caused by the power supply being under
powered or low quality.

I'd recommend looking at smartmontools and what you get out of 
smartctl -d scsi -x /dev/....

Look for Non-media error count and if its increasing with each message.

At the end of the output there's typically a SAS SSP section that lists
other link related counters that the drive is tracking.  I just looked
at one of my systems and the hba doesn't show any link issues (via
sasinfo) but the drive has registered several Invalid DWORD count,
Running disparity error count, and Loss of DWORD synchronization events.
This system isn't producing any disk or hba error messages so this may
be common or typical.
