I just upgraded my 486DX33 system from 8M to 16M of ram and I am
having problems.  I am running 386bsd-0.1 + patchkit-0.2.1 +
keycap-0.1.1 + julians scsi drivers and the system was very stable
before the upgrade.  I have used the same kernel binary on a 486DX266
with 16M of ram with no problems.

Basically, since the upgrade, the machine is prone to spontaneously
reboot when it is being worked fairly hard in 386bsd.  Most recently
it crashed while trying to compile tif_fax3.c from the xv-2.21
distribution (which can take upto 30M of virtual memory and
consequently gives the memory system a good workout).

I thought I had fixed the problem after I removed the SIMMS and
replaced them in a different order but it seems to have come back.

I ran a couple of DOS memory test programs.  One of them (ramtest from
Brown Bag software) locked up the machine completely about 3% into its
extended memory test but had no problems at all with the expanded
memory test.  The other (testext by J.M.Cyr) ran all night with no
errors.

It seems likely that I have a hardware problem here but I guess it
could be 386bsd.  Does anyone have any ideas?  I don't want to mess
about getting my dealer to replace the memory if it isn't going to fix
the problem.
