Some weird errors on my UNIX pc these days.

[Lenny Tropiano]

I've been experiencing some weird errors the last two days, and I am
attributing them to one of three things.  

   1.  Installation of the 3.51a kernel from the fixdisk [ie. bug in kernel]
   2.  Installation of EIA/RAM board w/1MB of memory.
   3.  Change of IC chip on EIA board revision J as per the HOTLINE's 
       instructions.

Or maybe all had something to do with it.

First error occured yesterday... I wasn't home so I don't know the sequence
of events that lead up to it:

	panic:  trap vector 4
	double panic: trap
	...
	[repeated about 5 times]

I woke up today and saw the [!!] error icon, and I pressed it and saw:
Does this mean the devil is in my machine? ;-)

	+----------------------------------+
	|System Error                      |
	|                                  |
        |         /proc/06666              |
	|                                  |
	| Touch ENTER ...                  |
	+----------------------------------+

I then proceeded to examine /usr/adm/unix.log for anything weird.  I had
the customary "Spurious interrupt .." and the "FDERR" from floppies, and
at the end I had:

NMI (parity error) at 0x2FFBC0 (*hpte: 0xE1F7) Thu Mar 31 18:03:15 1988

NMI (parity error) at 0x82200 (*hpte: 0x41EB) Sat Apr  2 06:05:25 1988

NMI (parity error) at 0x82200 (*hpte: 0x41FF) Sun Apr  3 03:46:23 1988

This to me sounds like a MEMORY problem.  0x82200 sounds like something
on the motherboard, and I assume the larger hex address 0x2FFBC0 is
the extended memory.  Sounds like time to run diagnostics again :-{
