Question Laptop hangs when booting after soft-reset (after hard-booting to GNU/Linux)

Hello GNU/Linux experts.

This is a dual booting (GRUB 2) UEFI 64-bit laptop.

If I hard-boot (shut-down the computer and turn it on manually) to GNU/Linux (Debian, Ubuntu, different kernels, up to 4.0.4) the system works fine, but if I reboot (shutdown -r now, reboot, init 6), when the computer starts again it will ALWAYS hang when loading the operative system (it doesn't matter if I choose GNU/Linux or Windows 8.1).

When booting GNU/Linux it hangs at "loading initial ramdisk...", or sometimes it passes it but hangs right afterwards, at the first line of systemd. When booting Windows 8.1 it doesn't display any message, it hangs shortly after showing the Windows logo.

Now here's an interesting thing: If I hard-boot into Windows 8.1 and I soft-reset, then the computer will boot to any system without any problems. And not only once, I can reboot for an unlimited amount of times any system. But this ends if I shutdown or sleep the computer. Then the problem is here again, unless I hard-boot to Windows again.

To put it more graphically, the boot order can be WIN->ANY-OS->ANY-OS, etc. But it can never be GNU/LINUX->ANY OS.

I don't know why this happens. I've been reading a lot but I haven't found info of anything like this anywhere so I hope someone here can tell me where the problem might be. I'm ready to do any suggested tests or post any outputs needed. All ideas will be much appreciated.

This is propably ACPI bug. Is your laptop very recent?

Report the bug in appropriate mailing list. Hope someone fixes it.

Question
UEFI misconfiguration or restriction? or Linux (kernel) ACPI bug?

Quote:
This is propably ACPI bug.
Yes, maybe a very subtle bug that ends up ruin everything. What would be the best way to troubleshoot this particular bug?

Remember that I can boot GNU/Linux with the problem already fixed (rebooting a hard-booted Win 8.1) or with the problem preset (hard-booting to GNU/Linux), so maybe I can check some logs or do some tests in order to find a difference in the system.

Which one would it be?

Quote:

I'm afraid yes, and it isn't very common. I bought it weeks ago, but I think that this motherboard/BIOS is a year old at the most. It's one of those hybrid laptop+touch-screen. It works really well with Windows 8.1, but configuring Debian has been very hard so far.

The computer is generic and I don't know the make and model of the motherboard because those DMI data fields are empty and I couldn't find it when I opened it. It has an Intel Celeron N2807 microprocessor.

This is some BIOS info:

Code:
AMI BIOS
Core version: 5.009
Compilancy: UEFI 2.3: PI 1.2
BIOS VERSION: B14AP254
EC VERSION: E14AK115
EC DATE AND TIME: 06/05/2014

CPU-> Microcode Patch: 809

Intel GOP Driver: 7.1.1005

TXE Info:

Sec RC Version: 00.05.00.00
TXE FW Version: 01.01.00.1089

At the POST screen, it displays:
AMI Bios 1AREF015, Ver. 2.16.1242 2013 05/15/2014
Quiet boot = disabled
Fast boot = disabled
Secure boot = disabled
BIOS Read/Write protection = disabled

I installed both systems with secure boot disabled.

As a second possibility I think this may also be a BIOS/UEFI misconfiguration, but I investigated every BIOS setting and I couldn't find the problem. In case anybody thinks this is the reason, these are the variables that efivar --list returns:

I can access them all as root and print their content, but these few return an Input/Output error:

8be4df61-93ca-11d2-aa0d-00e098032b8c-KEK

d719b2cb-3d3a-4596-a3bc-dad00e67656f-db

I could post the output of all of them, but it would take me a lot of time and I'm not sure it would help. Perhaps somebody knows what variables may be interesting to investigate and post.

I compared each and every one of them after hard-booting Windows 8.1 and after hard-booting GNU/Linux, and they are exactly the same. The only one that changes every time one boots is 01368881-c4ad-4b1d-b631-d57a8ec8db6b-MonotonicCounter, which seems to be a boot counter. I also compared the dmesg and I couldn't find any difference.

Just for the record changing almost all BIOS/UEFI settings I thought were related didn't help. For instance, disabling SMI didn't make no difference.

The ACPI bug hypothesis seems the strongest so far.

I hope somebody can shed a little light on this.

I have some news.

If I hard boot to GNU/Linux and hibernate, then I can reboot/restart all the times I want (just like if I had run Windows).

So the only two ways to be able to soft-reboot and restart correctly the computer is hibernating GNU/Linux or booting Windows.


Graphically:

GNU/Linux (hibernate) -> ANY OS
WIN 8.1 > ANY OS

So I'm leaning towards the hypothesis that this is a Linux (kernel) problem. How can I find out what is wrong?



BONUS:
I don't know if this information helps, but I tried these boot options and this is my outcome:

BOOT
Acpi=ht Reboots? No.
pnpacpi=off Reboots? No.
Noapic Reboots? No.

DON'T BOOT
acpi=off
Pci=noacpi
Acpi=noirq
nolapic
