Bug Description

The log check triggers on grumman for the following line:

"WARNING: CPU: 0 PID: 376 at /build/linux-A2zmBZ/linux-4.4.0/drivers/dma/ioat/dca.c:342 ioat_dca_init+0x17c/0x1a0 [ioatdma]()"

This is part of a one time warning which says: "APICID_TAG_MAP set incorrectly by BIOS, disabling DCA" which points to a BIOS issue.
