there is the thread "[v3.10-rt / v3.12-rt] scheduling while atomic in
cgroup code" where I applied Mike's patch. This should fix the problem
reported and be part of the next release.
Could please double check (either by grabing the patch or waiting for
the next release).
I've applied Mike's patch from here:
https://lkml.org/lkml/2014/6/21/11
and tested it on the old dell core2 that reliably showed the splat
at boot, and it is now gone. This is on vanilla 3.14-rt plus isci
fix + simpleworkqueue + aio-swq fix (all pending for 3.18-rt next).
I also tested it on the 20 core canoe pass where the rawlock
conversion patch from Thavatchai caused strange and unpredictable
failure modes and that box seems fine with this smaller footprint
cpulight change.
Paul.
