Hello together,
i have many of this messages in my syslog:
Failed to stop TX DMA, queues=0x104

i have read in other posts, that this is a kernel issue.
Is there a easy way to update the kernel from 3.10.36
i am using WA850RE as a relayd (Ar71xx).
I have tried already:
edited trunk/target/linux/Makefile (changed Linux_Version to 3.12.10)
copied trunk/target/Linux/ar71xx/patches-2.10 to patches-3.12 and config-3.10 also to 3.12
recompile ..
In my last compile i forgot to copy the patches and the config, resulting in brick my device.
Is this all, or have i forgot something ?

There is no easy way to upgrade the kernel. You would need to manually update/correct/modify all the ar71xx-specific patches to reflect the changes upstream in newer kernels.

And the error is a famous one:

https://dev.openwrt.org/ticket/11862
and several other duplicates.
