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
