Bug#971696: linux-image-4.19.0-11-armmp: network hangs, oops in ath9k_htc after upgrade
Package: src:linux
Version: 4.19.146-1
Severity: important
Dear Maintainer,
since the last kernel update (from linux-image-armmp:armhf
4.19+105+deb10u5 / linux-image-4.19.0-10-armmp 4.19.132-1 to
linux-image-armmp 4.19+105+deb10u6 / linux-image-4.19.0-11-armmp
4.19.146-1) our BeagleBone Black systems with AR9271 based WLAN adapter
(ath9k_htc driver) print a kernel warning or oops during boot and all
network related system calls hang, breaking not just WLAN but also
ethernet:
=== Begin ===
root@mavis:~# ip addr
[no output, just hanging]
=== End ===
Kernel oops (from one boot):
=== Begin ===
[ OK ] Started Network Manager Script Dispatcher Service.

The information below (gathered by the reportbug scripts) is from a boot
without the AR9271 attached.
Please let me know if you need further information or if I should test
anything.
If there's a git repository I can *cross*-build from with reasonable
effort I can try git bisect.
