Comment(by dsd):

 The free_irq during suspend behaviour was added in
 a715dfc7b9ef15ed5b398b185bd84cc015ff37f6. Is IRQ releasing during suspend
 really a good driver practice? Might be able to find some answers in
 http://thread.gmane.org/gmane.linux.kernel/322862/focus=322978 and

 It doesn't look like the suspend routine goes to any great lengths to
 actually prevent the hardware from generating interrupts.

 This is probably a separate issue though. The test kernel posted above
 should hopefully clarify the order of events and explain why we seem to be
 doing mmc work so late in suspend.
