No power off after upgrading the kernel

mike934

I upgraded the kernel from 2.6.25-gentoo-r9 to 2.6.26-gentoo-r4. I just took the .config from the previous kernel, ran "make menuconfig" and saved it without modification. Everything seems to work fine with the new kernel except that power does not want to switch off after I press "Turn off computer" in KDE. What do I do to fix it?

I'd suggest when using the .config of a previous kernel to do make oldconfig before doing a make menuconfig.

Yeah I know that too, but if you copy your .config from one kernel to another, then you really need to run this :

Simple question: does 'poweroff' typed in the console work ?

hoacker,
I have CONFIG_CLASSIC_RCU=y and CONFIG_PREEMPT_RCU is absent in my configuration.

Hi,

I had the same problem but it disappeared when i upgraded to 2.6.27-r7. So it looks like there was a bug in the 2.6.26 kernel.
