When I try to build the new 2.6.38 kernel, I get the follosing error:

drivers/built-in.o: In function `nouveau_pm_acpi_event':
nouveau_pm.c:(.text+0xbfe89): undefined reference to `power_supply_is_system_supplied'

Please attach your kernel .config
Did you run "make oldconfig" after upgrading your kernel?

No, I didn't. I usually copy the ".config" file from the old kernel folder to the new one and then do "make menuconfig", "make", "make modules_install", "make install" and that's all. Is it a wrong way?

You could try it.

Try setting CONFIG_POWER_SUPPLY=y
(I think you will find it is set to 'm')

Yes. It had been set to 'M'. I set it to 'Y', then run 'make oldconfig' and then it compiled fine.
So, changing the "CONFIG_POWER_SUPPLY" parameter to 'Y' IS a solution, not obvious for me though.
  Anyway, thank you for the tip! Now I can use the new kernel. :)

I think an #ifdef CONFIG_POWER_SUPPLY before the function would fix the problem, without having the user to change kernel config.

I sent an email upstream.
