Bug Description

[Impact]

These are hw revision based workarounds from 6.2 that need to be backported for Intel Arc/DG2.

[Test case]

We don't have known issues that these would fix, but check that things still work normally.

[Where things could go wrong]

these are limited to a very specific type of hardware, so can't think of what could go wrong

This bug is awaiting verification that the linux-oem-6.1/6.1.0-1008.8 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-jammy' to 'verification-done-jammy'. If the problem still exists, change the tag 'verification-needed-jammy' to 'verification-failed-jammy'.

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!
