Question I am using X10DRi with BIOS 1.0b and IPMI 1.67. It is running Linux. It is spitting out the following: “ WARNING: CPU: 4 PID: 1421 at drivers/dma/ioat/dca.c:697 ioat3_dca_init+0x1a8/0x1c8 [ioatdma]() ioatdma 0000:00:04.0: APICID_TAG_MAP set incorrectly by BIOS, disabling DCA " “ Answer Please update to BIOS 1.0c which will fix Direct Cache Access (DCA).
