Subject: Oops/Warning report for the week of March 28th 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 oopses 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 538 oopses and warnings have been reported,
compared to 169 reports in the previous week.
