Thanks Manuel; unfortunately the generic kernel is not affected by this
bug, only the variants (aws, azure, realtime, etc), so we can't verify
with linux-generic.
I don't have permission to access the packages for the RT kernel in the
Noble ppa [1] (linked from [2]) but this bug/fix applies to all variants
so I tested with linux-azure. 1ecc312 (in noble) is clearly applied but
I'm still seeing issues here. I'm going to keep digging into this and
will post what I find.
```
