Fix shutdown for Intel BayTrail (Asus T100TA)

Description Adrian Chmiel 2014-02-01 11:35:44 UTC 
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. Broadcom BCM43241SFKFFBG TN1322 P24 294688 P3T -> WiFi on SDIO 
3. Phison PS2251-68-5 UO1329C D75J0.11AA -> USB 3.0 controler 
4. Realtek ALC5642 D2L87HI GD13F -> Audio 
5. Winbond 250(Q)64FW1G 1329 6236 QP30003 -> Memory with UEFI 
6. Intel Q326A657 SR1M5 02962 '12 -> CPU 
7. M F20 P02 CFQ0589 (No idea) 
8. ITE IT8568VG 1331-AXO ZC0P1A (No idea) 
9. SANDISK 9.15 XC4*00 SanDisk32G -> eMMC disc 
10. HannStar J 94V-0 E89382 1335 MV-4 -> Camera module

What about "halt -p" or poweroff ?
Comment 2 Adrian Chmiel 2014-02-01 17:47:16 UTC 
It's the same do.
Comment 3 Alan 2014-02-03 10:46:40 UTC 
Known problem. Patch already pending to at least make reboot work.
Comment 4 Bernd Kuhls 2014-02-08 22:15:01 UTC 
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?

Here is a screenshot of the error I am seeing when powering down or rebooting the system.
Comment 6 Stanislaw Gruszka 2014-02-13 15:34:30 UTC 
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 ?
Comment 7 Adrian Chmiel 2014-02-17 17:31:18 UTC 
Probobly patch is not included, because I test 3.14-rc3 kernel and still I can;t turnoff computer.
Comment 8 Bernd Kuhls 2014-05-17 14:24:14 UTC 
The bug is still present in 3.14.4.
Comment 9 Adrian Chmiel 2014-05-19 14:24:06 UTC

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.
Comment 13 Alan 2014-05-20 10:54:11 UTC 
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)
