Sorry, I might be wrong. Just checked the stacktrace again and it seems like the failure is happening in early boot in this report. Though the error "Unable to handle kernel paging request at virtual address" is happening in the function mem_cgroup_from_obj(). Naresh, can you repro the issue if you revert the patch "net: set proper memcg for net_init hooks allocations"? _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
