Public bug reported:

Bionic still has that old version from 2013
Debian have a more recent version: 
http://metadata.ftp-master.debian.org/changelogs/main/a/acpi-support/acpi-support_0.142-8_changelog
Actual source: http://www.uefi.org/acpi

Kernel (upstream) is supposed to have fixed the problem:
https://github.com/torvalds/linux/blob/eceeae414edccb07fad683011c0c65abe8a3a554/include/acpi/acpixf.h#L195

Does ubuntu kernel apply that patch ?
https://bugzilla.kernel.org/show_bug.cgi?id=117671

Because kernel 4.15.0-9 still log these errors:

kernel: ACPI Error: [\_SB_.PCI0.XHC_.RHUB.HS11] Namespace lookup failure, 
AE_NOT_FOUND (20170831/dswload-210)
