I think, this bug is associated with commend for hardware to turn off or etc. When I shutdown system (using for example "halt") system does everything right, but not turn off hardware. Last line is: [ 6063.591767 ] reboot: Restarting system _ And nothing else do. Hardware: Netbook ASUS T100: 1. Amtel MXT1664TXES-C2U 1330B TW QLG9F -> touchscreen controler 2.

What about "halt -p" or poweroff ?
It's the same do.
Known problem. Patch already pending to at least make reboot work.
I am seeing a similar problem using an AsRock Z87 Extreme4 system after upgrading from kernel 3.11.10 to 3.13.1. @Alan: Could you please point me to the patch you mentioned so I can test it?

Not sure what patch Alan has in mind, you can check latest upstream 3.14-rcX kernel, if it fixes the problem. Additionally your kernel is tainted by some module, does the problem also happen if you are not using proprietary driver ?
Probobly patch is not included, because I test 3.14-rc3 kernel and still I can;t turnoff computer.
The bug is still present in 3.14.4.

(In reply to Adrian Chmiel from comment #9) > This patch eliminates problem: > https://github.com/jfwells/linux-asus-t100ta/blob/master/patches/009-poweroff Tested the patch without success, my system still does not powerdown. Also I am having the same crash while trying to reboot, which is not addresses by your patch afaics. My system is not based on Intel BayTrail btw, it´s an Intel HSW system, using an AsRock Z87 Extreme4 mobo.
Backporting these patches did also not fix the problem https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/patch/arch/x86/kernel/reboot.c?id=a4f1987e4c5489a3877eaa7451a68d28c5a3f664 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/patch/arch/x86/kernel/reboot.c?id=fb3bd7b19b2b6ef779d18573c10c00c53cd8add6 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/patch/arch/x86/kernel/reboot.c?id=5be44a6fb1edb57d7d2d77151870dcd79c8c0e58
Different system, almost certainly a totally unrelated bug. However your system is also running non-free modules, so you'd need to start with the provider of those or build and test a kernel without any 3rd party stuff loaded. My guess is that a kernel without any non-upstream stuff will reboot fine but if not then please update (probably best to open it as a new bug as it's in fact very different to this one)
