Public bug reported:
Intel wifi card crashes anytime it tries to connect to 802.11ax AP (also
happens while roaming). Probably a ucode issue. `options iwlwifi
disable_11n` helps, but this reverts me to speeds suitable 10 yrs ago
(20mbps max). Tried every single ucode in `linux-firmware` repo which
are applicable, from -72.ucode to -89.ucode - didn't help. Tried other
options that disable power save, bt_coex etc., also didn't help.
