This bug is awaiting verification that the linux/6.5.0-16.16 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-mantic-linux' to 'verification-done-mantic-linux'. If the problem still exists, change the tag 'verification-needed-mantic- linux' to 'verification-failed-mantic-linux'.
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.

(AMD Radeon Pro W7500) Observed a bunch of [Hardware Error] messages and finally amdgpu crashed. [Fix] AMD provides a patch to fix the issue https://www.spinics.net/lists/amd-gfx/msg99737.html which is included in v6.7-rc1 7f3e6b840fa8 drm/amd/pm: Fix error of MACO flag setting code [Testcase] 1. Connect the DUT to an external DP monitor via one of the ports on the AMD graphics card 2. Boot into Ubuntu 3. Unplug the DP cable from the DUT 4. Wait for 30 seconds 5. Replug in the DP cable 6. Make sure the system doesn't hang and the external DP monitor works [Where probles could occur] The patch make sure MACO is supported only if BACO is supported. It creates a stricter rule for MACO to avoid MACO is enabled with BACO supports. It should be safe to apply stricter rules to enable features.
