(In reply to Thomas Rother from comment #3) > Created attachment 791056 [details] > acpidump Base on DSDT and SSDT, there have different reasons for different AE_NOT_FOUND error: - For _SB_.PCI0.XHC_.RHUB.HS11 This is the same issue likes some Dell machines. It's already fixed in openSUSE Leap 15.1 kernel. This issue will not be fixed in openSUSE Leap 15.0 because the ACPICA must be updated. - For \_SB_.PCI0.LPCB.H_EC.* I didn't find any definition for H_EC in DSDT or SSDT. I think that this AE_NOT_FOUND error will not be workaround even on ACPICA.
