bisect kernel result,
the patch 2c7b4bfadef08cc0995c24a7b9eb120fe897165f causes this regression
thermal: core: Store trip pointer in struct thermal_instance
Replace the integer trip number stored in struct thermal_instance with
a pointer to the relevant trip and adjust the code using the structure
in question accordingly.
The main reason for making this change is to allow the trip point to
cooling device binding code more straightforward, as illustrated by
subsequent modifications of the ACPI thermal driver, but it also helps
to clarify the overall design and allows the governor code overhead to
be reduced (through subsequent modifications).
The only case in which it adds complexity is trip_point_show() that
needs to walk the trips[] table to find the index of the given trip
point, but this is not a critical path and the interface that
trip_point_show() belongs to is problematic anyway (for instance, it
doesn't cover the case when the same cooling devices is associated
with multiple trip points).
This is a preliminary change and the affected code will be refined by
a series of subsequent modifications of thermal governors, the core and
the ACPI thermal driver.
The general functionality is not expected to be affected by this change.

Title:
Some DUTs can't boot up after installing the proposed kernel on Mantic
Status in linux package in Ubuntu:
In Progress
Bug description:
During the SRU testing for 6.5.0.33 kernel, I found some machines freeze at
very early stage of booting process.
The last messages displayed on the screen are:
EFI stub: Loaded initrd from LINUX_EFI_INITRD_MEDIA_GUID device path
EFI stub: Measured initrd data into PCR 9
There are no journal logs existed when it boot with the 6.5.0-33
kernel.
Here is the list of the impacted machines that I found so far
