Re: 2.4.19: sym53c8xx problems

[Mr. James W. Laferriere]

	Hello Eyal ,  I have a CP6000 unit (PPRO's tho) & am having no
	such difficulties .  Now that said I rebuilt the WHOLE scsi
	layout in the system in order to get rid of those older hotswap
	cages (imo, they stink electrically) .  Btw , Stable as heck .
	Wheres that forest I need to knock on ;-)

	Is your scsi setup easy enough to make an ascii art description
	of ?  If so would you post it please ?  From the messages below
	it appears (to me) that their is some difficulty in the chain that
	attaches to the python .  I have never seen those messages when I
	have attached (albeit differant) tape drives , ie: DLT,dat2,dat3 .
