Bug Description

The zram smoke has failed with:
  modprobe: FATAL: Module zram not found.

From its config, there is no zram related entry, not sure if this is intended:
  grep -i zram /boot/config-3.13.0-142-generic

(returns nothing)

If this is intended, we can disable this test on ppc64le.

ZRAM was not enabled for trusty 3.13, so I'll blacklist this as this test is invalid for this kernel across the supported architectures.
