Our BSD system on occasion gets a CMAP Busy panic during bootup.
It seems to happen after everything has come up (all the daemons have
started and you even have a Console Login). The full message is:
pmap_zero_page: CMAP Busy
Perusing the source lead me to: pmap_zero_page() in /i386/i386/pmap.c
Should this worry me? (e.g. should I run around backup everything and wait
for the inevitable) or is this some kind of a rare race condition
that I can live with.
BTW - I've seen this only after I upgraded the memory from 32MB to 64MB.
