A very clear distribution this time: the number one is almost 4 times
more frequently reported than the number 2. It's also an old time favorite,
with over *56 thousand* total reports..... time for the graphics team to fix the issue!
Other old timers are the ct_vm_map() function (over 11 thousand reports) as well as
various "your bios is broken" warnings.

There's also some recurring networking issues, with tcp_recvmsg and inet_sock_destruct
as main functions there.

New this time is a warning in the cpufreq code, which somehow now gets called
with interrupts off just when it wants to do a smp_call_function() during suspend resume;
also new is an interaction between ext4 and the quota code. Also new is an ioremap leak check
that might be a Fedora-only issue.


This week, a total of 16542 oopses and warnings have been reported,
compared to 14309 reports in the previous week.
