Public bug reported: [ 0.016192] ACPI Error: [\_SB_.PCI0.XHC_.RHUB.HS11] Namespace lookup failure, AE_NOT_FOUND (20150930/dswload-210) [ 0.016195] ACPI Exception: AE_NOT_FOUND, During name lookup/catalog (20150930/psobject-227) [ 0.016222] ACPI Exception: AE_NOT_FOUND, (SSDT:xh_rvp08) while loading table (20150930/tbxfload-193) [ 0.021348] ACPI Error: 1 table load failures, 7 successful (20150930/tbxfload-214)
I have noticed this ACPI error persisting in my syslog and dmesg. Based on what I have learnt from ACPI, acpitool -w and lspci, I think the error is related to Namespaces provided in the DDST on \_SB_.PCI0.XHC_.RHUB.HS11, which I think concerns the Root → System bus tree → PCI bus → USB controller: Intel Corporation Sunrise Point-H USB 3.0 xHCI Controller (rev 31) in my system. I have not found what .RHUB.HS11 refers too. I have tried changing my UEFI USB settings but to no avail. Appreciate help to fix this bug.
