Run Away scsi_eh_1 , Load was still climbing .

[Mr. James W. Laferriere]

	Hello All ,  Loaded a cdrom into a HP-2100 cd-rw for reading
	or I had hoped to .  did a mount .  & the little critter did the
	obvious thing & just kept on flashing its light at me .  So I hit
	the unload button which it did for about 500ms and reinserted
	itself .  Then the flashing light quit after about two iterations
	of flashing & stop & restart flashing .  Then the load began to
	climb ~ .15 Load avr. every 5 sec. ,  at about 2.0 I punched &
	help down the unload button & removed the cdrom .  At that time
	the load began to drop & scsi_erh_1 went back to sleep .
	Some specifics below .  Hth ,  JimL
