Re: [Xen-devel] [adhoc osstest bisection] complete test-amd64-amd64-xl

[Ian Campbell <ian.campbell@xxxxxxxxxx>]

The osstest instance in Cambridge appears to have found a machine
specific failure which a bisect has blamed on the "x86/domctl: cleanup"
patch below.

(NB: this is not the arm releated leak check thing which is currently
hitting the xen-unstable flights in the main osstest instance)

Since the logs are internal I've put a copy of the bisection output at
http://xenbits.xen.org/people/ianc/tmp/bisect.osstest.test-amd64-amd64-xl..html

Along with the logs of the first two passes from the last good revision:
http://xenbits.xen.org/people/ianc/tmp/37537/
http://xenbits.xen.org/people/ianc/tmp/37541/
and the logs from the first two fails from the first bad revision:
http://xenbits.xen.org/people/ianc/tmp/37540/
http://xenbits.xen.org/people/ianc/tmp/37542/

The failure is in migration at e.g.

http://xenbits.xen.org/people/ianc/tmp/37540/test-amd64-amd64-xl/17.ts-guest-localmigrate.log

Anyone got any thoughts on this?

Ian.
