The following reply was made to PR port-mips/48628; it has been noted by GNATS.

From: "Nick Hudson" <>
Subject: PR/48628 CVS commit: src/sys/arch/mips
Date: Sun, 11 May 2014 07:53:28 +0000

 Module Name:   src
 Committed By:  skrll
 Date:          Sun May 11 07:53:28 UTC 2014
 Modified Files:
        src/sys/arch/mips/include: pmap.h
        src/sys/arch/mips/mips: pmap.c pmap_segtab.c
 Log Message:
 Deal with incompatible cache aliases. Specifically,
 - always flush an ephemeral page on unmap
 - track unmanaged mappings (mappings entered via pmap_kenter_pa) for
   aliases where required and handle appropriately (via pmap_enter_pv)
 Hopefully this (finally) addresses the instability reported in the
 following PRs:
 PR/44900 - R5000/Rm5200 mips ports are broken
 PR/46890 - upcoming NetBSD 6.0 release is very unstable / unusable on cobalt 
qube 2
 PR/48628 - cobalt and hpcmips ports are dead
