- On a Romley box, the following message is displayed in the logs:
+ The kernel tries to load the KVM module for each CPU even though it
+ really only needs to be loaded once. For each subsequent load, the
+ kernel is trying to allocate the per-cpu area before it checks if the
+ module is loaded already. This can result in the following backtrace:
[ 8.294573] PERCPU: allocation failed, size=304 align=32, alloc from reserved chunk failed
