Re: geom<->ata forever cycle

Personally I dont think this is GEOM related.  I had a drive start doing
this to me (happens often as I work in a large datacenter) and the drive is
about to die.  What brand drive is it and how old is it?  You may waanna
look into replacing the drive if you have that option.  I had one tonight
that did that to me, swap the drive, fixed.
