Bug#602935: xen-linux-system-2.6.32-5-xen-amd64: domU stack trace error when migrating with xen kernel 2.6.32-27
Hi,
Google finds the same crash at
http://www.chiark.greenend.org.uk/~xensrcts/logs/2449/test-amd64-amd64-pair/guest-debian.guest.osstest-console
which is apparently some sort of testsuite log. It says that the
version was 28a160746815. Then in the same directory hierarchy I found
that the first non-failing version is
http://www.chiark.greenend.org.uk/~xensrcts/logs/2473/test-amd64-amd64-pair/guest-debian.guest.osstest-console
which says "this 6c72eadd151f6f1b904989532a83988af0ea661a, baseline
d0054d672ff0ebf6116cee27bae3fc2591c726af" -- I have no idea if the bug
was fixed or the test was changed.
Ian, I noticed you were hosting the testsuite results so I hope it's
ok to Cc you about this bug. Can you enlighten us on whether the
failing test has already been fixed? For reference here's the
beginning of the failing flight 2449:
