Hi,

I would request beaglebones users (either Black or white) to do some tests about a possible
cma=64M to be set on kernel cmdline:

# sed -i 's/^ABC_BASEARGS="\(.*\)"/ABC_BASEARGS="\1 cma=64M\"/' /etc/sysconfig/arm-boot-config
# a-b-c
# reboot

By default cma is set to 16 and is not enought for some cases: (see rhbz#1127000)
The goal is to see how it behaves on bb

Journalctl -b currently shows:
  cma: CMA: reserved 16 MiB at 3e800000
At should show 64 MiB on the next boot.

What would be nice to test is for possible regression on memory usage or else.
I let the cma conservative camp to provide any appropriate tests to support theirs arguments:
