Hi all,
I have some good news for you. I was able to fix the issue with the P.A.
Semi Ethernet. It was a problem with the new DMA handling. The patch '

Michael,
Maybe a DMA issue. Please find attached an output of strace.

Looking at the changes in pasemi I don't see any significant
Hi Michael,
Thanks a lot for your answer. We tested some vanilla mainline 4.3
kernels on an Electra reference board. Additionally we tested some
patched 4.3 kernels on our Nemo boards.
It would be really fantastic, if you could fix the problem.
Cheers,
Christian

Hi all,
We tested some 4.3 kernels on a P.A. Semi reference board. Ultimately,
ethernet does not work, though on the reference board, the interface is
detected, gets link, but will not pass any packets/traffic.
Somewhere in the source code of the commit "'powerpc-4.3-1' of
Hi All,
I compiled a lot of kernels for some git bisects and I have a result.

Hi Denis,
Thank you for your answer. Sorry because of my description.
Yes, the driver probe function finds the device.

Hi All,
I have tested the PA Semi Ethernet with the kernels 4.2.3 and 4.3.0
today. With the kernel 4.2.3 it works but with the kernel 4.3.0 final it
doesn't work.
After that I tested some git kernels and release candidates of 4.3.

Hi All,
Does the ethernet interface on your Electra, Chitra, Nemo, and Athena
board work with the release candidates of the kernel 4.4? Unfortunately
the P.A. Semi ethernet doesn't work on our Nemo boards with the release
candidates of the kernel 4.4. We have set the following entries in the
