Sorry for the last mail ... the correct DTLB and ITLB error messages
are:

[using 456936 bytes of netbsd ELF symbol table]
pmap_bootstrap: could not claim physical dseg extension at 3eca0000 size
360000
Setting DTLB entry 00000000 01000000 data e0000000 3f400074
Setting DTLB entry 00000000 01800000 data e0000000 3e400076
Setting ITLB entry 00000000 01000000 data e0000000 3f400074

Eduardo already says that this error is difficult to trace and correct but
I hope analysing the pmap_bootstrap message someone could detect
what is wrong.

Thankful ...

Neilson
