I'm already using a current version of May (1.5V), so the
problem is still there.
The pmap is derived from i386 code, because the mmu of the
MPC860 resembles more the i386 than PowerPC.
The basis for it should be several month old. Have there
been any changes to pmap that, if not incorporated, could
cause this bug?
However, could you give me a hint what could be wrong? I fear
next thing I have to do is understand pmap...
