Hi again,

in the meantime, I have some more information to add to the issue mentioned in
my email quoted further down below.

Ben Greear approached me off-list and suggested to try the Candela Tech ath10k
driver and firmware and see if the issue occurs with that as well. So, for the
last 3 weeks I've been testing the CT driver and firmware and I can happily
report that the issue with the driver crashing after a while when a Nexus 5X
device is connected is not occuring with the current BETA 18
firmware-2-ct-full-community.bin. So, this really seems like a regression in
the official API level 5 ath10k firmware blobs.

The CT firmware is not perfect either, since it seems to suffer from a different
bug that has been resolved in the official firmwares, and that is that after a
reboot of my TP-Link Archer C7 v2, the ath10k driver won't load. Only after a 
hard reset or "cold boot" it will come up. That's an issue I had with older
official firmwares as well, but it has been resolved with the recent API level
5 firmwares.

Nevertheless, for the time being, I will stick to the CT firmware because I can
work around the reboot issue and having the 5GHz wifi working for my Nexus 5X
clients is more important.

Over the next weeks, I will test different combinations of ath10k(-ct) driver
and firmware to see if there's a combination that resolves all issues. This
morning I flashed a LEDE build with the official ath10k driver and the CT
firmware binary.

But of course, if someone has more suggestions on what I could try or what
information I could collect to help resolve the issue related to the Nexus 5X
clients in the official firmware binaries, I think that would be beneficial
for a larger audience.

Regards,

Timo

P.S.: Please include my email address in any reply, since I'm not subscribed
to the mailing list. Thank you.
