Does anyone know what causes OS/2 to crash with the message;

An unmaskable interrupt has occurred
TRAP 0002

Register dump

Internal processing error at 02xx:xxxx
The system is stopped

Or words to that effect.  I've been using IBM OS/2 1.2 S.E. for about 
7 months without seeing this error.  The appearance of the error seems to
coincide with the upgrade from 4Mb to 8Mb of ram - is TRAP 002 a parity
error?  I also recently installed the XR04053 CSD, could this be the problem?
The error occurrs at random intervals.  After well over an hour doing 8
separate compiles which appeared to be using all available RAM (according to
FREEMEM.EXE) and lots of heavy disc accessing the system stopped when
everything was finished and I tried to open a VIO screen.  The error does not
always coincide with opening a VIO screen though.
The computer I'm using is an Epson Equity II+ and an Everex RAM8000 memory
expansion card.  I don't have any other high current using expansion cards
so the power supply should be addequate.
Any help advice or suggestions would be appreciated.

P.S. Has anyone ever got the plotter driver for PM to work with PicPrint, for
either an HP plotter or an IBM plotter?

P.P.S. Does anyone know a phone number where technical advice about OS/2
can be obtained from IBM (such as what TRAP 0002 means).  The only number I
have gets me to a dealer routing service.  None of the dealers I've been
routed to know anything about OS/2 (ugh! whas tha, a new clone!!).
