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 :-{
