I was seeing this error with 5.4-RELEASE, on a machine with 4GB, and
when using PAE. Are you using PAE? If so, you'll need to either
upgrade to 5-STABLE or apply a 2 line patch to your 5.4-STABLE system
(the patch hasn't been committed to that branch yet, it should
probably be committed to 5-4.RELEASE-p*). You can find the patch by
searching the archives for "PAE" and "pmap.c".
