Comment 29 for bug 1932548

Hi Harrison,
Intel used to ask users using the latest proprietary firmware from upstream[1].
The proprietary firmware is a blackbox in opensource, so we are trying to figure out the stable combination of kernel and related firmware.

So far there are 2 kernel flavors verified works in the environment of #27 in Focal:
1. HWE kernel 5.11 + latest firmware iwlwifi-QuZ-a0-hr-b0-59.ucode (you can try it from the linux-firmware from #21 which is doing SRU)
2. OEM kernel 5.13 + latest firmware -63 (you can try it from the linux-firmware from #21 which is doing SRU)

We did not check the latest mainline kernel[2] + latest upstream firmware [1] because so far the above 2 works well in our WIFI AX environment.

We are wondering if any difference from the Steve's environment and yours keep the Intel proprietary firmware crashing.

Could you please check if the above 2 kernel flavors plus the linux-firmware doing SRUing work on your environment?
If it still failed, could you please share with us the dmesg and lspci (better to get sosreport as well) and which WIFI 6 AP you are connecting to? So that we can try reproducing your issue here :)
