Bug #2824
[linux-libre]: 5.7.3+ makes external (USB) ath9k devices unusable
0%
Description
Upgrading to linux-libre-5.7.6-1-x86_64 causes ath9k_htc to fail to initialize which causes the wifi adapter to not show up even though all modules are loaded.

It's fine to me, I use an ath9k device:
$ lspci
02:00.0 Network controller: Qualcomm Atheros AR928X Wireless Network Adapter (PCI-Express) (rev 01)
Subsystem: Foxconn International, Inc. Device e007
Kernel driver in use: ath9k
Kernel modules: ath9k
$ uname -r
5.7.6-gnu-1
$ lsmod | grep ath9k
ath9k 184320 0However, it didn't work for my external USB dongle (TP-Link TL-WN722N)
Users will temporally have to use linux-libre-lts

ok i added a news post already, suggesting that everyone installs the linux-libre-lts - i have an ath9k USB wifi thingy too - i will check it out

thats bad news then - i guess the news post advice needs to be changed

there are bug reports for this in arch and also in linux - it does not seem to be moving very fast though - the fix probably will not get in until at least 5.7.8
https://bugs.archlinux.org/task/67041
https://bugzilla.kernel.org/show_bug.cgi?id=208251
the patches which broke it entered in 5.7.3 - the last working version 5.7.2 is still on winston - maybe we should just pull 5.7.6 and publish 5.7.2 again
the last working LTS version is 5.4.44; but we do not have that anymore
or to fix 5.7.6, the bad commit has been identified, and it has been confirmed by several people , that reverting its changes fixes the prolem

i pulled linux-libre and linux-libre-headers 5.7.6 for all three arches, and re-released 5.7.2 - i left the linux-libre-docs, linux-libre-chromebook, and other kernel packages as they were
i thought that was best because the lts kernel has the same problem

linux-libre-hardened is still in 5.6, it's unaffected by this bug
maybe users should just use it in the meantime, rather than forcibly downgrading linux-libre
the fix probably will not get in until at least 5.7.8
so let's wait, then :)
we did sth. similar when a linux version broke i686, we just waited for the next release

I tested a few USB wifi antennas (one, with Atheros chipset and other, with Realtek). In the upstream version of the kernel, this bug has been present (at least, I have a PLC to use in my desktop PC). In my netbook with Arch, the Realtek blob does not be afected with the upgrade of the kernel.

Arch fixed this bug with this patch
I'm building linux-libre 5.7.8 right now
