Some more info on this, the user with a x250 is reporting
the problem is hard-freeze about once a day, which goes
away when disabling LPM, so if you have a 50 series Lenovo
laptop and are seeing the occasional hard-freeze this may
be the cause.

Serious problem with SATA LPM in F28 on Lenovo 50 series laptops

[Christian Dersch]

Hi,

should I also get the freeze from the F28 live media? I have a T450s
(which worked fine with your LPM test kernels few months ago) but cannot
migrate to 28 yet.

Greetings,
Christian

Yes, you should, but I just got the second of the 3 users reporting
this to confirm that on his T450s the hang happens rarely, say
about once a day, so unless you want to run the live-media for
a long time, testing with F28 live is not really going to be helpful.

The 3th reporter reports he can trigger the issue at will (on a
different model) by changing the LCD panel brightness, so if you
can give that a try that would be great. Please try changing the
brightness both through the hotkeys and through the system-menu
(top right menu of the gnome shell top-bar).

Hans

Serious problem with SATA LPM in F28 on Lenovo 50 series laptops

[Christian Dersch]

I managed to install F28 (fresh install of KDE spin) on the second disc
of my T450s. I cannot reproduce the issue by changing screen brightness
there with min_power and also the med_power_with_dipm default. I tried
it with battery only as well as with connected power supply. Now I'll
see whether I get that rare random freeze.

In attachment you find the information for my T450s and the installed disks.

Greetings,
Christian

Wow, thank you very much for doing all this testing, hopeful we will gain
some useful extra insight from this.

Serious problem with SATA LPM in F28 on Lenovo 50 series laptops

[Alexander Ploumistos]

Hello Hans,

I've just upgraded a G50-30 and like Christian, I can not reproduce the
issue. I logged into MATE and GNOME, played with the brightness settings
while plugged in and on battery, it did not hang.

It is good to hear that not everyone with a 50 series seems
affected, note though that of the 3 reporters so far only
one can reproduce with the brightness keys and the other
2 see a hard-freeze about once every 24 hours, so you might
be affected but not know it yet.

If you do experience unexplained freezes try disabling the
LPM, see:
https://fedoraproject.org/wiki/Common_F28_bugs#lpm-hang

And then wait for a few days to confirm the freeze is
really gone.

Regards,

Hans

So after 4 days of working with that installation (several hours per

Ok, so it seems that not everyone is affected, thank you for the
info.

Can you do:

cat /sys/class/dmi/id/bios_version /sys/class/dmi/id/bios_date

And let me know the output. Also related to this have you
updated your BIOS recently / are you in the habbit
of tracking BIOS updates? I'm wondering if this is BIOS
version related.

Regards,

Hans

Ok, so it seems that not everyone is affected, thank you for the
info.

Can you do:

cat /sys/class/dmi/id/bios_version /sys/class/dmi/id/bios_date

And let me know the output. Also related to this have you
updated your BIOS recently / are you in the habbit
of tracking BIOS updates? I'm wondering if this is BIOS
version related.

Hans

Serious problem with SATA LPM in F28 on Lenovo 50 series laptops

[Frantisek Zatloukal]

Hans,
can't this be affected also by different disk vendors (drive vendor in
Lenovo laptop can vary even in same model) and different firmware of disks?
Also, drive FW is upgradeable in Lenovo laptops.

Hi,
here is the output:

# cat /sys/class/dmi/id/bios_version /sys/class/dmi/id/bios_date
JBET68WW (1.32 )

I  apply BIOS updates quite regularly.

Normally this indeed is more disk then laptop/motherboard related
but in this case it seems that it is something motherboard related,
as several people are reporting this with very different disks and
1 reporter has even tried to swap the disk.

Thank you, may I also ask which desktop-environment you are
using (because of GPU usage by the DE)

I’m going to go out on a limb and suggest that the problem might be with
power management, not with SATA per se. On a modern Intel system, an NVMe
device that hasn’t internally gone to sleep will prevent the PCIe link from
going into an ASPM sleep state, and that, in turn, will keep the whole
system from going into a deep PCn state.  I could easily believe that
there’s a bug where nasty ACPI things like brightness hotkeys go terribly
wrong in deep PC states.  I would also believe that the lack of SATA LPM
will also block deep PC states.  And I’d believe that the laptop has an
electrical problem that only affects Linux for mysterious reasons.

As an experiment, could some affected users try running ‘while true; do
true; done” or otherwise pinning a CPU at 100% and seeing if the problem
goes away?

Yes in the mean time there is only one unsolved case of the 50 series
having issues with LPM on a SSD which is known to work with LPM for
others. This is likely a power-management issue.

It turns out that the user who was having issues with brightness
changes replaced his LCD panel with a non Lenovo part to get an
IPS screen in his laptop, so that one I've scratched of the list
as being due to the non OEM panel.
