ACPI error messages in dmesg on 6.0-BETA5

[martin hudec]

Hello,

  I am getting strange errors in dmesg on one of our servers. Are these
  errors something critical, or there is no need to pay attention to
  them? Errors are those with "looking up [xxxx] in namespace" as shown
  below.

	thank you,
	Martin
