Dear All,
I am using LEDE on my IPQ806x (QCA9980) system (Archer C2600).
With compat-wireless-2016-05-12, I observed traces attached below.
The router is unstable and eventually reboots by itself (randomly).
Upon reverting to compat-wireless-2016-01, the issue disappears. Nothing
else is changed (software-wise or hardware).
This was confirmed with other users.
A new compile with the fixes below:
https://git.lede-project.org/?p=lede/nbd/staging.git;a=commit;h=858e26f3c0fc11231f25497cbb2ddca1e5f101e0
Did not solve the problem.
Please let me know if I need to provide any further information.
