iwlwifi crash
Sometimes, the wireless NIC (AX210 in my case) crashes:

iwlwifi 0000:28:00.0: Microcode SW error detected. Restarting 0x0. iwlwifi 0000:28:00.0: Start IWL Error Log Dump: iwlwifi 0000:28:00.0: Transport status: 0x0000004A, valid: 6 iwlwifi 0000:28:00.0: Loaded firmware version: 71.058653f6.0 ty-a0-gf-a0-71.ucode iwlwifi 0000:28:00.0: 0x00000071 | NMI_INTERRUPT_UMAC_FATAL iwlwifi 0000:28:00.0: 0x00008210 | trm_hw_status0 iwlwifi 0000:28:00.0: 0x00000000 | trm_hw_status1 iwlwifi 0000:28:00.0: 0x004DAEA2 | branchlink2 (...)

A workaround with the microcode version above seems to change the power management scheme to 1 for the kernel module iwmlmvm. Don't disable anything in iwlwifi especially the 802.11n support at the cost of disabling the 5 GHz usage and having super-slow speeds. So either:
 * Add on the kernel command line => iwlmvm.power_scheme=1
 * Create a file in /etc/modprobe.d and add this statement inside => options iwlmvm power_scheme=1

With that setting alone, everything seems stable again no crashes in more than 8 hours of usage.
