Hi Colin, Did you every manage to find a fix for this 'panic: pmap_init: page = table page is out of range' panic when sensible amounts of memory are allocated to a = FreeBSD PV XEN kernel? I think you said that you were working on something in January.

The bug I fixed back in January was a panic on AMD CPUs with amdc1e (Xen gets unhappy when you try to halt the CPU...). The 'page table page is out of range' bug was mentioned at the time but I didn't have a chance to track it down (and I can't test that on EC2 since t1.micro instances only have 600 MB of RAM and the larger instance types don't work with FreeBSD for other reasons). I'll try to make sure this gets fixed before 9.0-RELEASE (~3 months off?) -- if someone can give me SSH access to a box where I can launch instances which show this bug, it will probably get fixed sooner (debugging via email is a nuisance...). -- Colin Percival Security Officer, FreeBSD | freebsd.org | The power to serve Founder / author, Tarsnap | tarsnap.com | Online backups for the truly paranoid From owner-freebsd-xen@FreeBSD.ORG Mon Mar 7 11:07:13 2011 Return-Path: Delivered-To: freebsd-xen@FreeBSD.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2001:4f8:fff6::34]) by hub.freebsd.org (Postfix) with ESMTP id 40625106567D for ; Mon, 7 Mar 2011 11:07:13 +0000 (UTC) (envelope-from owner-bugmaster@FreeBSD.org) Received: from freefall.freebsd.org (freefall.freebsd.org [IPv6:2001:4f8:fff6::28]) by mx1.freebsd.org (Postfix) with ESMTP id 142938FC1B for ; Mon, 7 Mar 2011 11:07:13 +0000 (UTC) Received: from freefall.freebsd.org (localhost [127.0.0.1]) by freefall.freebsd.org (8.14.4/8.14.4) with ESMTP id p27B7CYa097133 for ; Mon, 7 Mar 2011 11:07:12 GMT (envelope-from owner-bugmaster@FreeBSD.org) Received: (from gnats@localhost) by freefall.freebsd.org (8.14.4/8.14.4/Submit) id p27B7Cx3097131 for freebsd-xen@FreeBSD.org; Mon, 7 Mar 2011 11:07:12 GMT (envelope-from owner-bugmaster@FreeBSD.org) Date: Mon, 7 Mar 2011 11:07:12 GMT Message-Id: <201103071107.p27B7Cx3097131@freefall.freebsd.org> X-Authentication-Warning: freefall.freebsd.org: gnats set sender to owner-bugmaster@FreeBSD.org using -f From: FreeBSD bugmaster To: freebsd-xen@FreeBSD.org Cc: Subject: Current problem reports assigned to freebsd-xen@FreeBSD.org X-BeenThere: freebsd-xen@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Discussion of the freebsd port to xen - implementation and usage List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 07 Mar 2011 11:07:13 -0000 Note: to view an individual PR, use: http://www.freebsd.org/cgi/query-pr.cgi?pr=(number).
