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)
It has been a quiet week due to the holidays, only 55 oops traces have been collected.

Rank 9: mutex_lock Null pointer dereference Reported 2 times, of which one was a duplicate report Seems to be related to running PPP over a bluetooth link More info: http://www.kerneloops.org/guilty.php?version=2.6.24-rc6&guilty=mutex_lock&start=1574400&end=1574400
kerneloops.org news: * As of 2.6.24-rc6, oopses have a unique identifier which makes it possible to filter out duplicate reports of (and replies to) the same oops. Unfortunately some reporters remove this line from their reports to lkml.
