Thanks for confirming, good to see that the issue can be reliably 
reproduced with a setup similar to mine!

I wonder it it might be possible to revert back to the code in kernel 
6.10 (that worked fine), until the current issue can be triaged and fixed.

The other way round, I am getting the impression that other changes are 
getting stacked on top of the faulty ones, further complicating the picture.

As of today, with kernel 6.11.11, the issue has /worsened/ for me. On 
6.11.4 I could hibernate/resume by kfkilling bluetooth only, which was 
not so bad, since I only use bluetooth rarely. With 6.11.11 I need to 
rfkill the wlan too.

Can this be confirmed too?
