[Bug 2078041] Re: UBSAN: array-index-out-of-bounds in /build/linux-Z1RxaK/linux-6.8.0/drivers/gpu/drm/amd/amdgpu/../pm/powerplay/hwmgr/processpptables.c:1249:61

This bug is awaiting verification that the linux-xilinx/6.8.0-1009.10
kernel in -proposed solves the problem. Please test the kernel and
update this bug with the results. If the problem is solved, change the
tag 'verification-needed-noble-linux-xilinx' to 'verification-done-
noble-linux-xilinx'. If the problem still exists, change the tag
'verification-needed-noble-linux-xilinx' to 'verification-failed-noble-
linux-xilinx'.


If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.


See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

[Test Case]

Compile-tested only.

[Where Problems Could Occur]

Limited to AMD GPU drivers, so people with that HW might encounter any
type of issues.

[Notes]

Trace is from dmesg in bug 2077920.
