I often get this kind of message on one of my servers (which is NOT running X):

It's seems to appear when backuping on scsi2 tape. 

i wonder if this won't put the system into an instable state because
sometime the machine crash later with:

Now I restart the machine just after de backup and I will see...
Any idea of whate to do ?

I use 'dump' for my backups. The machine with AMD K6 processor have only
SCSI drives (no ide).
