Hi All,

As linux-6.15.1 came with the same Oops kernel panic I jummped into 6.14 
branch resulting in no issue up to 6.14.4

I observed that kworker/u16 was always cited in the panic report.

Grep -r kworker/u16 found the following report in

~.drivers/gpu/drm/ci/xfails/msm-apq8096-skips.txt

I am not sure if it is relevant to our present problem.
