Actually it matters if commit d9018976cdb6 is missing with this particular BIOS/system because every time you boot the system, the BIOS resets to default when it finds BCR register is changed. This is different issue than the CMP=1 issue most of the users have reported. This one also is not permanent so everything is fine as long as you don't touch that BCR register. In this case you either need to always boot to a kernel where that fix (d9018976cdb6) is included or blacklist lpc_ich.ko. Ubuntu v4.14.x kernels have that fix included so you might want to take one of them or build your own.
