Well, I don't know if I have any idea why it's doing it but I can report 
the same problem w/ my machine.  I've got a 3/50 with the 2.3 prom and a 
486/33 running linux.  Sometimes it would hang at getty, and core was 
dumping all over the place.  I did took some stuff out of the rc files 
and this helped a little bit but still couldn't have the machine up for 
more than a day or so.....

P.S. After I got a scsi drive for my machine and put everything on that, 
everything worked great, no core dumps or anything, just a slow scsi (for 
now).
