From: Volker Werth <vwe@freebsd.org> To: Wouter Snels <nospam@ofloo.net> Cc: bug-followup@freebsd.org Subject: Re: kern/127699: [panic] Fatal trap 12: page fault while in kernel mode Date: Sun, 05 Oct 2008 15:57:21 +0200 This is a multi-part message in MIME format. --------------020602030903030602040709 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit On 10/05/08 01:18, Wouter Snels wrote: > I ran ./vmcore.sh >/tmp/vmcore.log 2>&1 because it seems like there was > a lot of data which was still send to stdout and stderr, .. incase you > needed it, it should be in vmcore.log Wouter, you may also use the script(1) command which automatically stores stdout and stderr into a text output file. But redirecting stderr is also fine. I think we've gathered a lot of debugging info but we need to make one last step to find the cause of the panic. Can you please run the attached script and file the outcome to the PR? It will give us the values of some variables and I'm pretty sure a net maintainer will find what's causing your panic and can produce a fix for it. As soon as we've got the additional debugging information, I'll forward your PR to the appropriate maintainer(s). Thank you for your effort - I know it's been a pain for you to give me all the requested information, but we need that for analysis.
