ACPI Error kernel fail to assign BAR registers to PCI
device message in Ubuntu 16.04 LTS
Description: dmesg displays the following BAR failure messages on system startup:
pci :BAR 6: failed to assign [mem size 0x00100000 pref
Applies to: Ubuntu 16.04.3
Cause: The Linux PCIe layer tries to allocate all PCIe BARs in every boot. Home agent devices on Intel Xeon
processors are not expected to have BAR registers. The home agent devices however return a positive
value when queried by kernel.
Solution: This issue can be ignored because there is no functionality loss.
