memory bug??

[Karl Mehlhaff <kmehlhaf%crl.com@localhost>]

on a a4000 running Netbsd1.2 with a warp40/40 has anyone had trouble 
upgrading the memory from 64Mb to 96 or even 128?  As soon as I placed 
additional 32Mb 60ns simms into the warp, when loading a kernal I immediatley
get on the console:
pmap_enter_ptpage, cant get kpt page
illegal command
0xbba1e         unlk    a6

thought the memory might be bad, but amigaOS/wb has no problem,
weirder still, when I compile a new kernal and reload, it does not have a 
problem, but then the grfmodes I had been using with the picassoII 2mb 
prior to the memory upgrade and new kernal install, 
grfconfig reports back as bad monitor modes for all modes 1-8 for /dev/grf3??

any ideas/suggestions?

and I thought a memory upgrade was going to be easy........sure, plop in 
4 new 32Mb simms and whallah!.........ug!
