My DG AV-4000 is developing this error usually when swapping:

Unrecoverable memory fault at physical location FFF82034 (hex)
DG/UX System Panic. Panic Code 1000037.

This is an AV-4000 with a second CPU added, running DG/UX 4.31. It was
one year old last month....

Of course, I called DG. They said mail it in -- it can be ready in only 30
days!

I have rearranged the memory (32Mb of 4Mb SIMMS) in every configuration.
Same error, same address. I suspect this is a memory mapped device
of some sort, probably the integrated SCSI. 

If anyone has seen this error, knows what is at this address, or has 
a clue please contact me, preferably by email at:

ewillis@neuron.tamu.edu

Thanks.
