[q] SCSI HDD or what the problema ?

Hello!

When I compile a new world:

Feb 10 20:45:10 rosette /kernel: (da0:sym0:0:2:0): phase change 6-7 3_at_09b7518c resid=2.
Feb 10 20:45:10 rosette /kernel: (da0:sym0:0:2:0): phase change 6-7 3_at_09b7518c resid=2.

Feb 10 20:46:24 rosette /kernel: (noperiph:sym0:0:-1:-1): SCSI BUS reset detected.

but, server working done. compiling ended.

second messages without any compiling or other stress of disk:

This is a HDD/controller/etc problem ?
