OpenBSD 7.9 feedback: iwx powersave issue

Short summary

OpenBSD 7.9 introduced a WiFi driver bug affecting Intel AX200 chips on certain Lenovo laptops, triggered by newly enabled power-save features and 11a mode incompatibilities. Disabling power-save with the -powersave flag and forcing 11n mode provide temporary workarounds. This is a niche infrastructure issue requiring kernel-level debugging and dmesg analysis.
