I had a kernel panic recently with a 1.1 kernel.  I was moving two very large 
files on a zipdrive (scsi).  The files in question were the xc-1 and xc-2
tars from the X11R6 source distrib.  I have a core and kernel file.
Does anyone want them/can anyone make heads or tails of them? 
Is there a place I should look for info like this?
