This failure occured on joubertin1.  The joubertins were put into
service again yesterday after a long absence.  (The absence was due to
hardware trouble with the PDU etc. - not anything that would cause
this crash.)

So I think this is probably a host-specific crash.


The bisector has found a basis pass in 127489 and is working on it.
It has only just started.  In particular it has not yet repro'd either
the basis pass or the new failure, and right now it is doing some
rebuilds of old (expired) build artifacts to repro the basis pass.

Results will appear here:

  
http://logs.test-lab.xenproject.org/osstest/results/bisect/xen-unstable/test-amd64-amd64-amd64-pvgrub.xen-boot.html

and interim reports, or a report of a failure to bisect, will go to
the osstest-output mailing list under subjects like this:

  Subject: [xen-unstable bisection] 132970: testing 
test-amd64-amd64-amd64-pvgrub
