I manage to resolve this issue by adding cgroup_enable=pids to the grub boot command:
cgroup_enable=pids
# file: /etc/default/grub - GRUB_CMDLINE_LINUX_DEFAULT="modules=sd-mod,usb-storage,ext4 nomodeset quiet rootfstype=ext4" + GRUB_CMDLINE_LINUX_DEFAULT="modules=sd-mod,usb-storage,ext4 nomodeset quiet rootfstype=ext4 cgroup_enable=pids"
This issue does not occur on x86_64 architecture and seems to me only impact ppc64le. I am investigating if it is related to the fact that CONFIG_CGROUP_PIDS is not enabled in the linux-lts kernel.
x86_64
CONFIG_CGROUP_PIDS
linux-lts
FYI I've lodged a new Merge Request to enable CONFIG_CGROUPS_PIDS for linux-lts ppc64le (3.12-stable). This would address the issue at its root and users won't have to explicitly declare the cgroup_enable=pids in /etc/default/grub anymore.
/etc/default/grub
$ cat /proc/cgroups #subsys_name hierarchy num_cgroups enabled cpuset 2 1 1 cpu 3 1 1 cpuacct 4 1 1 memory 5 1 1 devices 6 1 1 freezer 7 1 1 net_cls 8 1 1 perf_event 9 1 1 pids 10 1 1 # <-- HERE IT IS :D
