Warning/Oops report of the week of September 16th, 2008

[Arjan van de Ven]

This is the first report where I've dropped oopses that happened to 2.6.25 or earlier kernels.
I've also changed the format of the report to split it in "fixed" and "not yet fixed" sections;
I hope that makes the report more useful for developers.



This week, a total of 1730 oopses and warnings have been reported,
compared to 626 reports in the previous week.

Some of these are undoubtedly from the atl1 driver, and many of those
from that driver are probably from me personally as I've poked around
trying to isolate the cause.  I sent a patch yesterday to Alexey
Dobriyan (who's also been experiencing it) that seems to quash the
warnings, so hopefully we're near resolution.  On my own development
system I recently turned off kerneloops, so at least *my* contribution
to the list will diminish.  :)
