Hello all,
I was testing 2.6.30-rc3-omap1 on n800 and noticed that idle power
consumption is very high, ten times compared to a 2.6.29 I tested few
weeks back. I'm guessing that CPU doesn't sleep at all.
Is this a regression? How should I debug this further?

Oh yeah, I forgot to mention that I have included Jarkko's patch "ARM:
OMAP: Fix tusb6010 init error and compilation warning" in my builds.
Otherwise usb won't work.

Between .29 and .30, the PM code in l-o was dropped and re-sync'd to
kernel.org code. This is so that PM can be separated out into a
separate branch and submitted upstream independently.
The current PM branch is in the process of being re-based onto 2.6.30.
When it's ready, I'd appreciate any testing on n800.

Ah, of course. I read about this but didn't understand the implications :)
Thanks for pointing this out to me.

Ok. Please let me know when it's ready.
