I am having problems trying to get my AlphaStation 200 to boot a kernel 
built from the -current source I supped this morning.  The kernel builds
however when I try to boot of the new kernel, the boot process halts 
with the following error right after the "Regents of (etc)" copyright is
displayed:

	panic: pmap_enter_ptpage: can't get KPT page
	halted

The machine has an up to date set of boot blocks.  Any one have any idea
what is going wrong?
