Subject: recovery from suspend is broken with recent libreboot + linux-libre
 4.7
Date: Wed, 27 Jul 2016 08:58:30 +0000

Following this[0] thread you can see the problems I have with libreboot
latest (latest at the time of flashing) experimental release.

Leah later said - an email or log I can not find at the moment on
libreboot or libreboot-dev - that this behavior was fixed with
a T400 system running parabola with linux-libre 4.6.4.

I know more people than just me are using libreboot here, do you have
any problems with suspend and recovery?
Can you test (if your system is already libreboot testing, if not wait
for either the next release candidate which should happen soon or be
ready to unbrick it) and provide logs so that we can fix it in our
system?

Hi,

I have a X200 and some time after waking up from suspend on the first larger disk access it hangs, losing all the dirty sector payload in the process. This is Guix-specific, the same machine works just fine on Ubuntu.

I don't update the BIOS (I disabled the ability to do so in the chip settings).

Given the ability for an update to brick, I only flashed it once before there was any data on the machine - and I don't plan on doing it again on this machine.

I do actual work on this machine and were it not booting it would be much worse than wakeup not working.

I sometimes non-thinkingly close the laptop lid so it crashes from time to time. So if logs help I can provide those.

Also, dmidecode stopped working some time ago so I can't check which libreboot version I have.

This seems to be normal for GuixSD.  I don't have much knowledge about
how the kernel and drivers here are packaged and configured, maybe some
/dev/ devices are left out or we have more restriction than 'standard'
systems. With libreboot and Gentoo, or at least with coreboot and Gentoo
dmidecode worked… I think. I know that it works when I flash from ubuntu
livedisk.

Output for me (if not already written in my logs) is this:
# dmidecode 2.12
SMBIOS 2.7 present.
8 structures occupying 386 bytes.
Table at 0x7DAA0020.

/dev/mem: Operation not permitted
Table is unreachable, sorry.

This is the boot up messages of one of the affected (running GuixSD)
devices. As I was assured this is a GuixSD specific problem, parabola,
trisquel and others do behave as expected (recover from
suspend/hibernate works).

I am used to individual configured kernels, so this might be just my
impression. Should this not be more specific, include core2 etc, or is
this just a listing of vendors there and not the cpu selection I
remember from the makemenuconfig dialog?

Then further on there's a call trace, this will be pasted here and leave
out some lines because I don't like to be that transparent in clear
public communication about my hardware.  Then again I don't know how
much this will tell, so if anyone says it's easier to debug with the
full information provided, I could do so.  This trace happens every time
I boot:

It's unlikely to be Guix-specific.  More likely, it's related to the
kernel version.  On several occasions in the past, new kernels have been
found to have problems on Libreboot systems.

We include older kernel versions: linux-libre-4.4 and linux-libre-4.1,
which you can select via the 'kernel' field of the OS configuration,
e.g.: (kernel linux-libre-4.4)

Can you try these and see if the problem persists?

For what it's worth, linux-libre-4.7 works well for me on my Libreboot
X60.

I tried these kernels and still have the problem (with GuixSD +
libreboot x200).

I had my original problems (see subject) on 4.6 and 4.7. It is likely
that they appear on earlier kernels too.

I will try to test 4.1 and 4.4 when I have the time, but I doubt it
changes anything.

Mark, Clèment: Do you run the release or the testing version of
libreboot?

I reproduced with both stable (20150518) and beta
(experimental-86-g07ed7f9).

For each one of them, I tried linux-libre 4.1, 4.4 and 4.7 without
success.

Note that my system is encrypted (except /boot).

My machine just crashed with a Linux oops (with blinking caps lock and everything) - the second time it did that, ever.

I have crashkernel enabled - but unfortunately the kernel that Guix installed didn't have all the flags enabled that I need to be able to generate the crashdump.

See http://dedoimedo.com/computers/kdump.html#mozTocId967714

Also, I have 2 CPUs and kdump only supports 1 CPU :(

What's the standard way to recover just the oops text? I didn't see any text.

I'm running an older Libreboot release on my X60: 20150126

Can you setup a serial console or a netconsole ? That should help you
get the logs.

I have an X200s with the 2015 release of libreboot.  I’m using the 4.1
kernel and have no problems.

AFAIR suspend problems on X200 and similar are a known regression in the
current version of libreboot.

I think this is more or less coreboot and libreboot related.
Libreboot is working on it[0], and I'd rather sit on this bug until it
is solved upstream. Testing t400 image now could mean to repeat the
disassemble,reassemble procedure if I get a brick[1] ;)

I just flashed the latest stable of libreboot and for t400 it is fixed,
I can recover from suspend. Thanks to the amazing work of Leah and all
other libreboot contributors :)

Additionally: We have to include in our documentation either a link to
how to deal with debbugs (specifically: how to close bugs) or if it's
not already existing, create it in Guix contrib documentation and
upstream it.
I have no clue how to close this bug, and upstream website is not good
in providing info.

This is probably a libreboot bug, because it is reproducible with
Debian.  Closing it.

Libreboot is probably involved, but it's a combination of libreboot +
linux-libre upgrades fwiw.

I'm running an X200 with an older version of Libreboot.  I just verified
that Linux 4.10.X still suspends fine, but 4.11 fails to suspend.

Anyway, not saying it shouldn't be closed, but maybe useful information
for people to have.

I've reproduced the bug with Debian testing (linux-nonfree 4.9 +
libreboot stable).

Thank you, it is interesting indeed!

While chatting on #libreboot the other day, and I've been told that this
might have been fixed upstream (coreboot), but that the fix introduces
random "forced suspends" every week or so.  I'm going to try, as I
prefer my computer to shut down every week than not being able to
suspend to ram.
