[Bug 1584407] Re: Ubuntu 16.04 LTS --> Kernal --> ACPI Errors: Namespace lookup failure and 1 table load failures


SunBear, thank you for reporting this and helping make Ubuntu better.

As per https://www.asus.com/us/Motherboards/Z170M-
PLUS/HelpDesk_Download/ an update to your computer's buggy, insecure,
and outdated BIOS is available (1803). If you update to this following
https://help.ubuntu.com/community/BIOSUpdate does it change anything?

For more on BIOS updates and linux, please see

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful.

Also, you don't have to create a new bug report.

Once the BIOS is updated, if the problem is still reproducible:
1) Please provide the output of the following terminal command (not perform an apport-collect):
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
2) Please make a comment specifically advising on if there was an improvement or not.
3) Please mark this report Status Confirmed.

If it's not reproducible, please mark this as Invalid.

Thank you for your understanding.

  Ubuntu 16.04 LTS --> Kernal --> ACPI Errors: Namespace lookup failure
  and 1 table load failures

Status in linux package in Ubuntu:

Bug description:
  [ 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.
