Hi Mark,

I have seen this error several times and tried to report it
yesterday to the list. (Subject: 2.4.0-ac4 lockups)

I mainly see this when in X and prolonged network activity is
taking place. Running something like Netscape seems to favour
this to happen, but I have seen this happen when using the
console (Alt-F1/Alt-F2) and changing the console fonts using
consolechars.

Magic SysRq to sync fails with messages very similar to yours,
but not always in kswapd. So you are not alone in seeing this.

(Sorry about formatting of the text, Lotus Notes is not to
good for mailing-list usage...)

Hi,

I am running 2.4.0 final. I got the following failed paging request which produced a complete freeze.

As you can see it was precipitated by cron starting to run some housekeeping stuff overnight.

Has anyone else had prblems?

Mark
