Subject: [sched-devel/latest] WARNING: at mm/slub.c:2443

I got the following warning while running sched-devel/latest.

I was not doing any tracing at that point (for the glibc compilation issue). 
I suspect it was while I was using a KDE application (amarok) as the 
desktop froze for a few seconds at one point.

Cheers,
FJP
