[LEDE-DEV] [BUG] Kernel crashes with ath10k radio and Nexus 5X clients

Sat Oct 29 13:19:15 PDT 2016

Hi everybody,

I have a TP-Link Archer C7 v2 running a fairly recent build of LEDE (r1952, 
Linux 4.4.26, compat-wireless-2016-10-08). It all works well except for the
fact that when I connect a Nexus 5X device to the 5GHz radio, the kernel or
ath10k driver will crash after a while. 5Ghz wifi will be dead after that
until I reboot the system.

This issue has been reported before [1] and it also has been declared as
solved with newer firmwares [2] (but reopened by other users). However, even
with the latest firmware 10.2.4.70.58 from Kalle Valo's Github repository the
issue is far from resolved. I have tried many different firmware revisions
over the time (more recently 10.2.4.70.56 and 10.2.4.70.54), and I can could
only find that the issue sometimes takes longer to trigger with some firmwares
(which might just be random), but it would always occur at some point with API
level 5 firmwares. With API level 2 firmwares (which I testesd when I was
still using OpenWrt 15.05) I never saw these crashes, but the Nexus 5X had
other connectivity issues with these older firmwares that made this
combination no fun to use either. But this shows that the firmware itself
makes the difference here.

I actually have two Nexus 5X on my network (my wife's and my own). I can
trigger the crash with either one of them. And if both Nexus 5X are connected
to the 5Ghz radio, then the issue triggers much faster (can be as low as 15
minutes). My workaround is to let the Nexus 5X devices only connect to the
2.4GHz radio. This way, the device can runs for weeks without any issue or
crash, but of course I would prefer the actual bug being fixed rather than to
circumvent it.

I'm appending a syslog from my access point with a crash happening while one
Nexus 5X was connected to the 5GHz radio starting from the time the system
booted. I randomized the MAC addresses. but left the first two characters
unique so different clients can be distinguished.

If there is more info I could collect to help identify the cause of this
issue, please let me know (and possibly how to do that as well).

Thank you and regards,

Timo
