Hello
I have an hostapd setup with a
01:00.0 Network controller: Ralink corp. RT2790 Wireless 802.11n 1T/2R PCIe
The setup work fine on 6.18.26-gentoo
It breaks on 6.18.33-gentoo
I found an hint in dmesg:
On 6.18.26-gentoo I see:
May 31 15:48:45 trash01 kernel: ieee80211 phy0: rt2x00_set_rf: Info - RF chipset 0003 detected
On 6.18.33-gentoo I see:
May 31 15:22:57 trash01 kernel: ieee80211 phy0: rt2x00_set_rf: Info - RF chipset 0006 detected
The RF chipset seems badly detected.
Regards

I do not see any rt2x00 related changes between upstream v6.18.26
and v6.18.33. Assuming gentoo does not provide own extra patches,
seems the issue be in some other subsystem, maybe PCI.
Then the best way get solution to the problem would be to find
offensive commit using git bisection:
https://docs.kernel.org/admin-guide/bug-bisect.html
You can also try if by a chance bug is not yet fixed in just
released v6.18.34
Regards
Stanislaw
