OK, I just realised that our kernel includes various non-upstream
patches (yet), some of which are executing during suspend/resume and may
be a contributing factor to this problem.
(the patches allow us to retain power to our SDIO wifi card during
suspend)
Nevertheless, any help on our battle to stable suspend/resume and the
other bits we're working on is always appreciated. :)
