[ARM32] panic when sshd responding

["Andy Shevchenko" <andy.shevchenko%gmail.com@localhost>]

Hello.

I've got a few times (not always) kernel panic on OMAP/H4 when a
remote client tries to connect to sshd started on OMAP. I'm using the
NetBSD-current (20080522). There is message and back-trace of it.

panic: kernel diagnostic assertion "(pg->mdpage.pvh_attrs &
PVF_KENTRY) == 0" failed: file
"/home/andy/prj/netbsd/netbsd.se-local/sys/arch/arm/arm32/pmap.c",
