Unfortunately either your nor my code does fix the BUG_ON() I see with
the numa kernel:
kernel BUG at mm/page_alloc.c:1848!
See below for the core dump. It looks like this happens due to moving
a mem block where first and last page are mapped to different numa
nodes, thus, triggering the BUG_ON().
Didn't triggered it on our NUMA hardware, could you provide your
config then we can have a try?
Config attached. Other configs with an initrd fail too.
hmm, we can't reproduce it on our hardware, do we need
to run some specific stress test on it?
Thanks
