Hello Rafael,
Hope you are doing well. I am Chaitanya from the linux graphics team
in Intel.
This mail is regarding a regression we are seeing in our CI runs[1] on
linux-next repository.
Thanks for the report, I think that this is a lockdep assertion failing.
If that is correct, it should be straightforward to fix.
I'll take care of this early next week.
Thanks!
On next-20231003 [2], we are seeing the following error

Details log can be found in [3].
After bisecting the tree, the following patch [4] seems to be causing
the regression.
commit d5ea889246b112e228433a5f27f57af90ca0c1fb

ACPI: thermal: Do not use trip indices for cooling device binding
Rearrange the ACPI thermal driver's callback functions used for
cooling
device binding and unbinding, acpi_thermal_bind_cooling_device() and
acpi_thermal_unbind_cooling_device(), respectively, so that they
use trip
pointers instead of trip indices which is more straightforward and
allows
the driver to become independent of the ordering of trips in the
thermal
zone structure.
The general functionality is not expected to be changed.

We also verified by moving the head of the tree to the previous commit.
Could you please check why this patch causes the regression and if we
can find a solution for it soon?
