Hi,
I think the problem has already been solved here:
https://gcc.gnu.org/ml/gcc-patches/2017-01/msg00736.html

would suggest that you give it a go.

aarch64-linux-gnu-objdump -dr
Hi,

Hi,
We've been running Ceph on 4 APM Mustang boards within Linaro, running stock
Ubuntu Utopic (problem occurs with Trusty too).
Essentially when I place the network under heavy load (by writing data
to a Ceph filesystem backed by 3xOSDs), I experience kernel crashes.
