Hello Ingo,

well, I guess You can add me as reporter, but this has been independently 
reported by others as well, as the bug got hit by quite a lot of people...
I'm afraid I won't add much to technical description of how this crashes the
machine apart from what has been discussed in this thread. But the reason why
this hurts us a lot is that it seems systems running RT tasks are affected in
particular, and many of our crashed machines were failover clusters running
pacemaker/corosync (which runs a lot of RT processes). And it really sucks, 
when both nodes of "high-availability" system crash in the same time :( 
So we were then forced to plan preventive restarts of some of those critical 
systems just to be sure they don't end up badly..

thanks to You all for taking a look at this!

cheers!

nik
