Description Stefan Esser 1995-03-21 16:20:01 UTC 
My system will not be connected to a LAN anymore, 
so I rebuilt the kernel without NFS.
The kernel built this way panics with a message:

	panic: pmap_zero_page: CMAP busy

at the first call to 'ifconfig'.

I tried to boot single user and issued an 
'ifconfig -a' command, same panic message ...

Fix: 

Use kernel with NFS defined.
How-To-Repeat: Build kernel with network devices ('de' and 'ed' 
in my case, no SLIP or PPP) and without NFS.

Boot into single user mode.

An 'ifconfig -a' command will panic the system.
