--- Comment #1 from cfr (reescf@gmail.com) ---
Lenovo ThinkPad X720 is also affected by this, but it is not sporadic, as far
as I can tell. Not once since installing my current kernel have I seen normal
behaviour following sleep.

The problem persists if the machine is rebooted. Only powering off and
restarting restores the expected behaviour.

The bug seems to be a regression. See
https://bugzilla.kernel.org/show_bug.cgi?id=196129. My machine was not affected
by the original bug, but the problem looks to be the same.

Following sleep:

cat /sys/devices/platform/thinkpad_hwmon/hwmon/hwmon7/temp*
0
1000
0
0
0
0
0
cat: /sys/devices/platform/thinkpad_hwmon/hwmon/hwmon7/temp1_input: No such
device or address
cat: /sys/devices/platform/thinkpad_hwmon/hwmon/hwmon7/temp2_input: No such
device or address
0
0
0
0
0
0
0

and

cat /proc/acpi/ibm/thermal 
temperatures:   -128 -128 0 0 0 0 0 0 0 0 1 0 0 0 0 0

Prior to sleep, only the second sensor is missing and acpitz-acpi-0 gives a
sane reading. Following, the first goes AWOL and acpitz-acpi-0 is stuck at 48.

Removing and reloading thinkpad_acpi makes no difference and, for me,
re-sleeping and rewaking makes no difference either.

I should have looked at the date of this report. The problem I'm seeing is new.
I installed a new kernel this week and the problem started then.

ArchLinux kernel package version is 5.11.4-arch1-1. I did NOT see this bug with
5.10.16.arch1-1.

--- Comment #3 from cfr (reescf@gmail.com) ---
I tried adding 

acpi.ec_freeze_events=Y acpi.ec_suspend_yield=Y

to my kernel command line and rebooting, but I never got past the screen
displaying the command. The machine froze and I had to poweroff. 

Is there a newer invocation I could try here?

The bug does NOT manifest if I boot linux-lts 5.10.21-1. Following sleep:

cat /sys/devices/platform/thinkpad_hwmon/hwmon/hwmon6/temp*
0
1000
0
0
0
0
0
38000
cat: /sys/devices/platform/thinkpad_hwmon/hwmon/hwmon6/temp2_input: No such
device or address
0
0
0
0
0
0
0

and the fan is at 0RPM, while acpitz-acpi-0 and thinkpad-isa-0000 temp1 are
both +38.0°C.

I have the same issue on X1 Carbon 5th generation (i.e. lacking of temp1 makes
the fan run in max speed) and the bug still exists in 5.11.7.arch1-1. Going
back to the lts-kernel (5.10.24-1) makes temp1 appear.

--- Comment #7 from Thorsten (s-cvhajmmblfsofmpsh@thorsten-wissmann.de) ---
Probably it's the same issue. However, here we know that the main issue is that
the first entry of /proc/acpi/ibm/thermal is erronously -128 some (or most) of
the time (so the fan is just a symptom, not the issue).

temperatures:   -128 -128 0 0 0 0 0 0 0 0 1 0 0 0 0 0

Iirc, the first entry is
/sys/devices/platform/thinkpad_hwmon/hwmon/hwmon*/temp1_input

(By the way, the second entry being -128 is fine)

Thank you.

Can the other reporters of this bug please also see if the latest BIOS resolves
this? ThinkPad BIOS updates are available on lvfs, so they can be done under
Linux through fwupdmgr.

The situation is NOT resolved / the same for me after the recent firmware /
BIOS update.

After updating to kernel 5.12.12(-arch1-1), the issue still existed, but only
after multiple suspend/resume-cycles (I couldn't find a deterministic way to
reproduce it). After a BIOS update I wasn't able to reproduce it anymore. The
BIOS now reports: UEFI BIOS Version: N1MET65W (1.50), Embedded Controller
Version: N1MHT31W (1.20), Machine Type Model: 20HQS3KG00. However, I do not
own/hold the laptop anymore, so I can't tell whether the issue returns after
running the laptop for a longer time (days, or so).
