biosbits test failing on origin/master

[John Snow]

Hiya, on today's origin/master
(2ccad61746ca7de5dd3e25146062264387e43bd4) I'm finding that "make
check-avocado" is failing on the new biosbits test on my local
development machine:

 (001/193) tests/avocado/acpi-bits.py:AcpiBitsTest.test_acpi_smbios_bits:
FAIL: True is not false : The VM seems to have failed to shutdown in
time (83.65 s)

Is this a known issue, or should I begin to investigate it?
