But I have also no idea what is causing this, I guess we are doing
something wrong with the PCI communication? That reminds me, you could
try this in case that helps:

Heh, I saw this pop up a day after I sent this and was wondering. Is
this something I'd need on the host kernel, guest, or both?
On the guest where ath11k is running. I'm not optimistic that this would
solve your issue, I suspect there can be also other bugs, but good to
know if the patch changes anything.
Looks the same here, didn't seem to change anything based on the
kernel logs.
Could you try this?
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/net/wireless/ath/ath11k/pci.c?id=39564b475ac5a589e6c22c43a08cbd283c295d2c
This reminds me, I assumed James was testing with ath.git master branch
(which has that commit) but I never checked that. So for testing please
always use the master branch to get the latest and greatest ath11k:
https://git.kernel.org/pub/scm/linux/kernel/git/kvalo/ath.git/
There's a quite long delay from ath.git to official releases.
Good to know, and I was not in fact using that branch. Rebuilt from
ath.git/master but still roughly the same behavior. There does appear
to be more output now though, specifically a firmware crash:
[ 2.281721] ath11k_pci 0000:00:06.0: failed to receive control

Ok, that's progress now. Can you try next try the iommu patch[1] we
talked about earlier? It's already in master-pending branch (along with
other pending patches) so you can use that branch if you want.
[1] https://patchwork.kernel.org/project/linux-wireless/patch/20231212031914.47339-1-imguzh@xxxxxxxxx/
Same result unfortunately, tried both with just [1] applied to ath.git
and at HEAD of master-pending.
Thanks,
James
