I got report that ?reboot/kexec does not work in recent kernels.

I tried both kexec and reboot in 2.6.38, and it worked ok. Maybe
config issue?

I think it's config issue. Never heard of this.

I've seen that on my zaurus a month or two ago. When kexeced to pxa-linux-2.6
then tried to kexec again. The last thing I've seen was Bye on the framebuffer
console and the machine freezed.

The basic kexec code has been stable and solid for a long time so kexec
failures are almost always hardware interaction problems.

Someone not stopping dma, or someone not putting the hardware in a state
that the next kernel can figure out how to initialize it.
