How to Fix ACPI Error : Namespace lookup failure
Whenever I boot up my PC I'm getting this error
[ 12.432182] ACPI Error: [\_SB_.PCI0.LPCB.H_EC.ECAV] Namespace lookup failure, AE_NOT_FOUND (20160831/psargs-359)
[ 12.432241] ACPI Error: Method parse/execution failed [\_SB.PCI0.B0D4._TMP] (Node ffff9de85a1f4410), AE_NOT_FOUND (20160831/psparse-543)
It seems like something is missing (for ex. library, package etc).
I'm ignoring this error from 7-8 months because it has no bad effect on PC my but I'm more interested in why am I getting this error? And if possible, How can I fix this issue?
