tnx! that is what i thought, but i'd rather ask.
if i do a char* pfoo = pmap_mapdev(addr, size) in smbios_attach(),
it stands to reason that i would want to do a pmap_unmapdev
(pfoo,size) in smbios_detach(), yes?
however, when i do this, it panics.
am i missing the point here?
tnx for all your help so far!
