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

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)
kernel: ACPI Exception: AE_NOT_FOUND, During name lookup/catalog (20170831/psobject-252)
kernel: ACPI Exception: AE_NOT_FOUND, (SSDT:xh_rvp08) while loading table (20170831/tbxfload-228)
