Fabio, > Do the stalls also happen on a pure 3.16 kernel?
Yes, we just tried this out overnight and we get the same stalls here. We have seen similar problems on a Zynq-based board. It might be worth noting that a common chip between all three boards is, for example, the KSZ9021RN, while the FEC driver, for example, only runs on the two iMX6-boards. > How can we reproduce the error? We mostly run SSH with benchmarks using NFS, it can probably be triggered by using only SSH with the following loop: # while : ; do ssh arm-card date; done Our (pure) 3.16 kernel uses the following config. http://lkml.iu.edu/hypermail/linux/kernel/1408.1/03045/config.gz (We have quite generously disabled a lot of sub-systems in our config.)
