That's not the first time the kernel folks have done that. They do it in
the crypto subsystem to hide messages that folks would want to see and
fix, like the random number generator having no entropy but startup
programs trucking on as if get_random_{u32,u64,int,long} succeeded.
It would be nice to see the problem fixed rather than covering them up.

Title:
ACPI Error: [\_SB_.PCI0.XHC_.RHUB.HS11] Namespace lookup failure,
AE_NOT_FOUND (20150930/dswload-210)
Status in linux package in Ubuntu:
Invalid
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

[ 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.
