I'm actually having a similar problem for a similar situation, but it's not serial
console related.  Setup:
Headless IIcx, nothing connected to ADB, PPP to powerbook over serial line, ethernet
to the 'net.  I'll just be running something and the machine will die
dead dead dead.  Just sit there doing nothing and not come back (for 
days -- it happened on a Saturday and I couldn't get into work to reboot it until 
Monday).

So, this isn't a serial console problem.  It might be a kerberos related problem
(seem to happen when I run krb-applications), but it seems weird that
it would crash the entire machine w/o dumping core.

Specs:
IIcx, 8 physical ram, 8-bit graphx card, ethernet card
Kernel: HWDIRECTSBC #56
Disks: Numerous SCSI and a Zip drive

I'll try the non-SBC HWDirect and see if that helps, but any ideas are
appreciated
