4.4, 4.6: camera and unlock buttons produce tons of interrupts (was Re: N900 sleep mode)

Hi!
quoted
gzipped config is attached.

Note that I'm still using NOLO. I enabled the sleep, then went to
runlevel 1. LEDs still stay on, 55mA power consumption. That was with
1 in off_mode.
Nothing idling for me with your .config.. And it seems slower to boot
compared to omap2plus_defconfig? Maybe because of the extra GPIO
interrupts?
Extra interrupts only happen when enable_off_mode is 1, so that should
not be an issue during boot.
Looks like you have 117 additional entries in .config enabled compared
to omap2plus_defconfig. Maybe go back to omap2plus_defconfig with minimal
changes and verify it idles properly first?

I'm suspecting it's some driver(s) you have enabled causing the
issue.
I guess so. Do you (or anyone else) have minimum non-modular config
for N900 that boots with video? Could I get lsmod from your system?
(Yes, I still have nightmares from getting .config that works).

Thanks and best regards,
									Pavel
