Bug description:
BDW-DE/EP/EX has an errata that results in a warning at boot
[ 1.821602] pci 0000:ff:1e.3: [Firmware Bug]: reg 0x10: invalid BAR (can't
size)
The problem is just the warning, there is no functional issue
Dell requested to hide the warning. The only way to do that is through a
Linux patch.
errata:
98 b308166 - BAR1 to BAR5 in HA returns non-zero values after writing
0xFFFFFFFF to it.
Problem: During BAR initialization the Operating System will try to access
BAR registers. Bar1 to
Bar 5 HA (Dev 0x12, Func 0 , 4 Reg 0x14 - 0x24) returns non-zero values after
writing
0xFFFFFFFF to it.
