[SRU Justification]

[Impact]

AMD Strix s2idle failure due to AMD VPE driver init.

[Fix]

One commit from v6.9-rc2 (also backported to v6.8.7).

[Test Case]

Try suspend stress tests:

$ checkbox-cli run com.canonical.certification::stress-suspend-30-cycles-with-reboots-automated

[Where problems could occur]

No.

[Other Info]

This should be landed to Noble and OEM-6.8 automatically when stable fixes are rebased, however we may need it before that.

========== original bug report ==========

AMD VPE (Video Processing Engine) behavior breaks s2idle for AMD Strix platform, so adding VPE power-up to ensure FW loading properly. The patch landed in v6.8.7, oem-6.8 will have it once rebased.

Fix landed to v6.9-rc2:

This bug is awaiting verification that the linux-oem-6.8/6.8.0-1006.6 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-oem-6.8' to 'verification-done-noble-linux-oem-6.8'. If the problem still exists, change the tag 'verification-needed-noble-linux-oem-6.8' to 'verification-failed-noble-linux-oem-6.8'.

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.
