[48002.777081] Enabling non-boot CPUs ...
I wonder if this is a result of upload_pm_data()''s use of mutexes,
which
being a sleeping synchronization operation, shouldn''t be done in an
interrupt-off context.
I''m also having the machine hang in the suspended state on resume
sometimes (that is, I open the lid/hit a key/press power to resume the
laptop, but the sleep light keeps pulsing and I can''t get it out of
that
state without a forced power-off. I wonder if these are related.
This is with the stock Fedora 19 kernel, but I don''t think there are
any
differences from upstream in this area?
Thanks,
J

Hence I was thinking it was Xen related.
