Hi,
I found the reason, why the ath10k driver isn't initialized properly after
reboot with backports 5.15.33-1. It is related to regulatory domain settings.
If I add the following code from backports 5.15.8-1
diff -upr a/drivers/net/wireless/ath/regd.c b/drivers/net/wireless/ath/regd.c

reg->current_rd = 0x64;
the driver does start after reboot.
I think, this a dirty fix only and something in the regulatory domain code is
wrong, since the ath9k driver doesn't have this problem.

Hi,
I've trouble with the following commit:
commit 3aa96efa24c13c6e0aafa5ad826f3f95a3bd74f9
mac80211: Update to version 5.15.33-1
After this commit the 5G wifi interface doesn't start properly. The interfaces are
visible with ifconfig, but it isn't visible on air. To get 5G working, I must
restart hostapd. I'm doing this with the following command 'wifi down; sleep 5;
killall -9 hostapd; sleep 5; wifi &'.
Any idea, what is wrong in mac80211 5.15.33-1?

Hi Hartmut,
Do you have some more details?
Not yet.
Do you see any error message in logread?
No. It looks similar. In both versions (5.15.8-1 and 5.15.33-1), driver and
firmware
are load and hostapd does setup the interfaces. The only difference is the first
output related to country variants from EEPROM, but I think this printed text
only.
It is different for ath9k and ath10k.

The nvmem-cell stuff is from me, because I did change, how the calibration data
is load for the ath9k at a tp-link wdr3600. This router doesn't have an issue.
The affected router is the tp-link archer C7 v2. I'm using the kmod-ath10k
driver and not kmod-ath10k-ct.
What hardware was this happening on?
Router is a tp-link archer C7 v2. Firmware for ath10k is qca988x.
Did it work again when you reverted the linked commit?
If I revert this commit only, backports-5.15.8-1 does work with further commits
too.

Hartmut
