I can't get ttyO2 wakeup to work on my Blaze with 3.3-rc5.  It works
fine with 3.2.  I've been trying to bisect and everything, but it's
difficult.  To start with, during my bisect, many patches seem to be
in a state where the compilation fails (one example is
'OMAP44XX_IRQ_PRCM' undeclared).

Anyway, what I found out is that after fcf6efa3 (ARM: OMAP4: PM: Add
WakeupGen module as OMAP gic_arch_extn) wakeup from the console
doesn't work anymore for me.  Then I tried to comment out the
omap_wakeupgen_init() call in  gic_init_irq() and that seems to
work... for a while.  At least until ff819da4 (ARM: OMAP3: CPUidle:
Make use of CPU PM notifiers) commenting out that line seems to work.
But it doesn't work if I comment out the line with v3.3-rc5.

And that's when I reckoned I've been using too much time trying to
figure this one out. :)

Does anyone know how to solve this?
