Ok, I know that this was probably discussed before, or it only happens to me,
BUT.. 

I have installed the patches posted earlier to allow me to boot from one floppy
which mounts root from the hard-disk and installs a small ramdisk for /tmp.

Anyway, the system crashes EVERY time I try to copy a file to the harddisk that
is larger than about 25k but from certain devices..

		DOSREAD -> Harddisk = Failure		(file > 25k)
		/tmp (ramdisk) -> Harddisk = Failure	(file > 25k)
		 
			 BUT

		Mounted floppy file system -> Harddisk = Success  (file > 25k)
		DOSREAD -> Floppy = Success		(file > 25k)
		DOSREAD -> /tmp (ramdisk) = Success	(file > 25k)

The crash is usually quite messy, including writing bad I-Nodes to the hard
disk, and locking the system up in such a way that CTL-ALT-DEL does not 
do ANYTHING.  Garbage is produced on the screen, or a repeating 'trap < 16'
message is produced.

If this has already been discussed, would somebody PLEASE send me hints/patches
or info?

Thanks,
