This is basically telling you that you have a slower device on the scsi bus than the initiator can handle.
There is a few things you can try.
1) Move your disk drive to the physical end of the scsi chain and if it
is a SE bus use a line forced perfect terminator.

2) put your 4000 on its own bus. It looks like you have one available.
/pci@1f,0/ID/scsi@3

3)If the resets happen quite regular than replace the disk target 1 / sd16

A probable cause for the late collisions would be a switch hard set and
a Sun box using the auto negotiate feature on hme0.

Make sure that both the switch and U10 are hard set or auto negotiating.
If you would like the hme settings email me.
