Please let me know all the patches you have added to your machine. It would appear that you are having some sort of hardware issue, but apparently you provided only part of what was in /var/adm/messages below, which makes it hard to say for certain. What you have below may be all related to a single device error (note the time stamps). Are you saying this occurs over and over again?
By the way, only the fix for CR 6587133 deals with repeated device resets. The "fix" for CR 6538627 just added to the logged message the reason for the reset and the fix for CR6564956 made it so that right after boot the single reset that was required would no longer be required. This reset was only once per port per boot.
