Description visigoth 2000-09-19 00:30:00 UTC
	Right now I am experiencing some really strange behavior with my
Dell servers.  Mounting a floppy, or accessing it via dd(1) causes a
system hang, (accompanied by a bios beep from the dpt card as though it is
being rebooted as well as the screen going dark).  I have quite a number of 
other machines which are dells which are not displaying this behavior, 
the only 2 things that I have been
able to discover as a parallel is the PM3334UW cards in all 3 of them, 
as well as so far having only tested it on dual capable motherboards.  I
have attempted hardware replacement of floppy drives (when I originally
thought I just had a bad floppy), booting SMP or UP kernels, as well as
makeing sure I have the most recent firmware on all the involved
boards...  there is also a little interesting tidbit in the dmesg from the
machines that they all have in common:

fd0c: hard error reading fsbn 16 of 16-31 (No status)

So far, testing includes machines
sup'd Sept 6th source (broken) all through Sept 15.  I know that it worked
back (way back) in early Aug. 

Rest of dmesg can be found at http://www.telemere.net/~visigoth/dmesg.txt

Fix: 

I wish ;)
How-To-Repeat: 
	On any of MY dell machines with a DPT PM3334UW controller in them, build a new kernel and try to dd(1) or mount the floppy file system...

Does this problem still exist with more recent sources?
