To clarify for those who weren't there, the reason for the laughter is
that when Arjan was demonstrating the kerneloops.org project, and at
the time a crash in the utrace was #6 on the highest number of kernel
Oops reported to kerneloops.org in the preceeding seven days. I just
checked, and the crash in utrace now has the distinction of being #3
on the most popular kernel oops for the past seven days. So the
comments where along the lines of Fedora merged *what*?
Unfortunately, utrace making the top-10 hit parade on kerneloops.org
probably didn't help its reputation of being something that should be
merged, at least in the short term.
I assume the problem is already known and fixed, but if not:
