on the same line as the tainted flag and 2 below the binary module that
is in use.... I assume Jiri is now working on reproducing this
untainted ... ;)

I've posted it even tainted, since this happened once after 50 h of reproducing
another bug so I guess I'll never have untainted "version" of it, because I need
to use the laptop in real life too :). If Venkatesh wants to fwd it to
/dev/null, it won't bother me, maybe somebody else will come with untainted
report some later...
