Hi ath11k experts,

I am currently using Fedora rawhide and have installed their
version of the 5.11-rc2 kernel. The ath11k driver is broken for
this laptop.

Here's a snippet of the dmesg:
[    3.845315] ath11k_pci 0000:55:00.0: WARNING: ath11k PCI support is
experimental![    3.845652] ath11k_pci 0000:55:00.0: BAR 0: assigned [mem
0x8e300000-0x8e3fffff 64bit]
[    3.845674] ath11k_pci 0000:55:00.0: enabling device (0000 -> 0002)
[    3.845708] ath11k_pci 0000:55:00.0: failed to get 32 MSI vectors,
only -28 available
[    3.845714] ath11k_pci 0000:55:00.0: failed to enable msi: -28
[    3.845728] ath11k_pci: probe of 0000:55:00.0 failed with error -28


I have also attached a full lspci output for the device in
question. I did see the previous thread about this hardware,
and I just wanted to provide another datapoint and see if
there is any way I can help with this.

This is a known issue and there are proof of concept patches in
ath11k-qca6390-bringup branch to get 9310 working:
