kerneloops.org report for the week of June 14 2009

[Arjan van de Ven]

Hi,

First, a word of thanks to the kernel.org team for helping to host the kerneloops.org database
on a real machine rather than a small virtualized host. Performance and continuity will be a lot
better in the new setup! 
(as a result of the transition and hosting issues on the original server, there was a downtime of 
two days, meaning that the total number of reports is lower than typical)


New sightings this report include the XFI driver, the i915 gem code and the DMAR code.


This week, a total of 4026 oopses and warnings have been reported
for kernels 2.6.29 and later. Reports for kernels earlier than 2.6.29
have been omitted from this report.
