>Description:
my alpha boot floppy had read "warnings": 

Warning, unexpected short transfer 8192/18432
Warning, unexpected short transfer 8192/10240

(!#%$^$ cheap media.  well, I did get it in the mail from AOL...)

it appears that ustarfs's error recovery code adjusts the destination
pointer and length after a failure, but doesn't adjust the disk
address.

>How-To-Repeat:
	try to boot alpha from bad floppy.  watch it appear to read
successfully, and then crump early in boot.

>Fix:
	
(untested, hypothetical): 
At the end of the loop in ustarfs_cylinder_read, add a 

"seek2 += xfercount;"
