Comment # 25 on bug 1187472 from Peter Aufner

I've also come across this conversation:
https://wiki.archlinux.org/title/Talk:Dell_XPS_13_(9310)

Some observations:
* The script suggested in the thread with regards to bluetooth indeed allows
the system to hibernate.
* But on resume Wi-Fi won't work.
* Removing the ath11k_pci kernel module before hibernate as suggested in the
Arch Wiki doesn't seem to help that either.
* I had a random boot where Bluetooth was suddenly functional but it is gone
again since.

With regards to Wi-Fi on resume, I observe the following errors in dmesg:

[  110.261998] ath11k_pci 0000:72:00.0: wmi command 16387 timeout
[  110.262013] ath11k_pci 0000:72:00.0: failed to send WMI_PDEV_SET_PARAM cmd
[  110.262022] ath11k_pci 0000:72:00.0: failed to enable PMF QOS: (-11

All the behaviors seem to be the same between the most recent release kernel
and the HEAD kernel (also the newer -3 one).

In case I can contribute anything elese, please let me know
