I've been testing kernel from 
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2073047/comments/7 for 6 
days now.
I'd continue testing for longer but without kernel headers for DKMS I am 
missing functionality I need.

So far zero issues, Bluetooth works across many suspend/resume cycles.
Aside from missing bluetooth error msgs on resume, log is pretty much identical 
to 6.8.0-3x.

The only weird thing I've noticed is severe degradation in AVX performance when 
compared to previous kernels:
```
[raid6: avx2x4   gen() 29422 MB/s] vs [raid6: avx2x4   gen() 18152 MB/s]
```

P.S.
I've removed bluetooth init errors from previous comment as it was a mistake on 
my part while comparing log files.
