Actually in this case the problems seem to be in the new wired ethernet
drivers using the linux DSA infrastructure (mtk_soc_eth.c and mt7530.c)
are causing the issues. I have had no luck narrowing down either fault
as every avenue i have explored has lead to a dead end so far.
One of the fault test cases i found the watchdog timeout was more
reliably triggered by using wifi -> wan traffic, but i don't believe the
problem is the wifi (mt76) driver, because the timeout is caused by
The old drivers in the v4.xx kernels worked fine in this regard, so its
something to do with the new DSA drivers.
The odd thing is Lan1-Lan4 use the same drivers, but do no exhibit the
issue, its constrained to the WAN interface.
