I'm thinking some subtle difference between R4k and R5k caches which

based w/ 2.6.15 kernel).
I also found what seems to be a related patch from OpenWRT but I have
no idea what it's supposed to solve as I could only find the raw
In any case I tried to apply it to my Lasat kernel, but using the
_atomic functions instead of _coherent just causes a much earlier
I will try said patch on my O2/R5000 and the sigma8634.
