iwlwifi-so-a0-gf-a0-77.ucode is listed as above.
Note that my WiFi chip is AC9560 as shown below and cannot work with
iwx driver. Currently, crash on boot are significantly reduced compared
with the time I've reported to bz@ in early phase of iwlwifi
introduction, but still unstable (fail to hear beacon as above [not
always], crash when repeatedly switching back and force with wired
em0, etc.). Maybe specific with some parts of AC9560, including mine.
