Has your wifi ever been working properly or what update made it crash?
Comment by Marcel Fest (cellebyte) - Tuesday, 17 December 2019, 20:58 GMT
My Wifi crashes all the time.
I think the kernel is causing the crash.
because the firmware between 20191118 and 20190923 is the same iwlwifi

loaded firmware version 46.6bf1df06.0 op_mode iwlmvm
Loaded firmware version: 46.6bf1df06.0

something with the op_mode is not working.

Non working:
* kernel version: linux-5.4.3.arch1-1-x86_64.pkg.tar.xz
* linux-firmware: linux-firmware-20191118.e8a0f4c-2-any.pkg.tar.xz

working:
* kernel version: linux-5.3.1.arch1-1-x86_64.pkg.tar.xz
* linux-firmware: linux-firmware-20190923.417a9c6-1-any.pkg.tar.xz

boot_log non working:

@loqs thankyou
Comment by Stefan (alian) - Wednesday, 01 January 2020, 10:50 GMT
This seems to be related to the bug I reported with https://bugs.archlinux.org/task/64774 (and not  FS#64703  which was set as duplicate), seems to be same hardware MEDION E2293 MD61290/YS11G, BIOS GeminiLake_YS11G_V1.0.21 10/10/2018 and same error occurs NMI_INTERRUPT_UMAC_FATAL.

The problem still occurs with 5.4.6-arch3-1 and linux firmware 20191220.6871bff-1.

Note: Status of this issue is still 'not closed/fixed', nevertheless, in my case wifi (Intel AC 9462) works again after upgrade to 5.4.10-arch1-1 #1
