While running a memory stress workload test on a 16 processor numa
system, I received a number of call traces like the following:

buffer layer error at mm/page-writeback.c:559
Pass this trace through ksymoops for reporting

The system did not crash and continues to run. If someone wants to look
into this and needs more information, let me know.

Thanks,
Mark.
