Thanks for the udpate!

Recently a collaborator updated the `nixos/nixos-hardware` repo's kernel version to `5.12.9` for the xps 9310 as wifi and bluetooth is working out-of-the-box for them now. I was excited to update and try this myself, however despite having the same kernel version (5.12.9), the same qca6390 fw version (fw_version 0x101c06cc fw_build_timestamp 2020-06-24 19:50) and almost the same system firmware version (them 3.0.3, me 3.0.4) I'm running into an issue where I get some `qmi` errors and then the wifi firmware ends up crashing. Here's the relevant dmesg output on my system:

$ dmesg | grep -e ath11

My collaborator's system (whose wifi is working) has the same output, but without the last 5 lines of errors:

~ » dmesg | grep -e ath11

Here's their PR that removes the patches and updates to the 5.12 kernel. https://github.com/NixOS/nixos-hardware/pull/298

I checked out the bug report mentioned by justin (https://bugzilla.kernel.org/show_bug.cgi?id=212059) however it appears to be unrelated... at least I don't see any of the same `qmi` errors, and their firmware at least runs long enough that they can connect to a 2.4GHz network.

Any ideas what might be going on here?
