I haven't had much chance to look at this (about 1/2 hour this morning),
but my tests show that tyhe nullfs problems are caused by a divide by
zero error at line 227 of vnode_pager.c (line 235 in the 2.2.2 version
of this code). My test was to ftp a file on a nullfs mounted filesystem
on an (not anonymous) ftp server.
f_iosize for nullfs, umapfs, and unionfs are set to zero so I can see
this occuring for any of these filesystems.
