--- Comment #7 from wendy.wang at intel.com ---
Issue cannot reproduce on another more re-worked BDW system(Rework ID:
R09,R11,R12,F29, R14,R15), so this is should be single old non-worked BDW board
failure, so can close this issue as not kernel code bug.

I checked tested two BDW system difference as below:

The good system CPU is x-bdw05 with GT2
x-bdw05 : stepping 3(BIOS stepping D) (id=0x1606 (rev 06)), Lynx Point 01 (B0
stepping) and Host bridge id=0x1604 (rev 06) 2Cores/4Thread, CPU Genuine
Intel(R) CPU 0000 @ 1.80GHz, GT2 200MHz; BIOS version: V67.R01; KSC version:
V1.16; BDW_ULT_PremiumBDW
U_Preprod_acm2661_VME_1.5MB_Unified_BIOS-67.1_ME-10.0.20.1198(Spi Full) 


The fail system CPU is x-bdw04 with GT1
x-bdw04: stepping 3 (BIOS stepping D)(id=0x1606 (rev 06)), Lynx Point 02 (B0
stepping) and Host bridge id=0x1604 (rev 06) 2Cores/4Thread, CPU Genuine
Intel(R) CPU 0000 @ 1.60GHz, GT1 100MHz; BIOS version: V67.R01; KSC version:
V1.13; 
BDW_ULT_PremiumBDW
U_Preprod_acm2661_VME_1.5MB_Unified_BIOS-67.1_ME-10.0.20.1198(Spi Full)
