Public bug reported:
shortly after updating this machine to hardy (thus trackerd went mad indexing
things),
I saw the oops below in my kernel log.
Machine is a Quad G5 PowerMac (64 bits powerpc kernel), though the problem
doesn't
seem to be in some powerpc specific area.
It -could- have been related to successive failures at using a USB DVB adapter
(the
driver may have been corrupting kernel memory) though unlikely.
