Public bug reported:
Closed lid on laptop at end of the keynote, which presumably made it
attempt to enter sleep mode. I don't know whether it did sleep or not,
but restored and ran fine for the 10:30-11:00 session. Then I closed
the lid again at about 11:00 and opened it in the next session, at which
point the system failed to resume with a kernel lockup (mouse cursor
showed but was not movable; vt switching didn't work; kernel call trace
was shown.
Looking through the syslog, the following appears to be the start of the
failure. Fwiw, I do have NFS (v3) mounts set up at home, which the
system does not have access to from here at UDS, so it should just
ignore them. I don't know if that's relevant to this error though.
