Subject: Top kernel oopses/warnings for the week of May 30th 2008

The http://www.kerneloops.org website collects kernel oops and
warning reports from various mailing lists and bugzillas as well as
with a client users can install to auto-submit oopses.
Below is a top 10 list of the traces collected in the last 7 days.
(Reports prior to 2.6.23 have been omitted in collecting the top 10)

This week, a total of 3670 oopses and warnings have been reported,
compared to 3029 reports in the previous week.



In addition to Fedora, Debian now has included the client application in their
default GUI install targets, thanks a lot for that!

This week, based on feedback, I've split the report into "untainted"
and "caused by proprietary drivers". Let me know if I should continue
doing this or if the old format was better.

As an experiment (on request) I've exported the database to text files (one file
per report) and stuck it in a git repository. You can take a look with
git clone git://www.kerneloops.org/
Suggestions for improving the format of this are obviously very welcome, as are
"yes useful" and "no not useful" comments. Again, this is an experiment, if it's
not seen as useful I may discontinue it.
