I started getting these messages on boot with the march kernels.

These sectors are obviously the ones reserved by bad144
It _could_ be that the track which those are on is bad, 

I currently have no sectors on the drive marked bad.

gabriella# bad144 wd0
bad block information at sector 623696 in /dev//rwd0d:
cartridge serial number: 0(10)
gabriella# 

Has anyone else noticed behaviour similar to this?
Any ideas?  It _seems_ harmless but I haven't tried bad144
with real arguments.
