https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D249987 --- Comment #18 from commit-hook@FreeBSD.org --- A commit references this bug: Author: wulf Date: Wed Dec 16 07:59:48 UTC 2020 New revision: 368689 URL: https://svnweb.freebsd.org/changeset/base/368689 Log: MFC: r367349, r367854, r368365, r368374(by cem) r367349: atkbdc(4): Add quirk for "System76 lemur Pro" laptops. Currently atkbdc(4) assumes all coreboot BIOSes belonging to Chromebooks and unconditionally sets a number of quirks to workaround known issues. Exclude "System76" laptops from this set as they appeared to be a traditional hardware ("lemur Pro" is a rebranded Clevo chassis) with coreboot firmware on board. KBDC_QUIRK_KEEP_ACTIVATED quirk activated for Chromebook platform makes keyboard on this devices inoperable. "Purism Librem" laptops may require the same exclusion too. PR: 250711 Reported by: nick.lott@gmail.com r367854: psm(4): Disable AUX multiplexer probing on all Lenovo laptops. Rudimentary AUX multiplexing support was added to kernel to make possible touchpad initialization on some HP EliteBook laptops with trackpoint. Disable multiplexer probing on all Lenovo laptops now as they use touchpad pass-through port rather than AUX multiplexer to connect trackpoint and at least two model (X120e and X121e) is known for getting PS/2 AUX port dysfunctional after switching back to hidden multiplexing mode. AUX MUX probing can be reenabled with setting of hw.psm.mux_disabled load= er tunable to 0. PR: 249987 Reported by: jwb r368365: atkbd(4): Change quirk table end-of-list marker to NULL vendor/maker/prod= uct This fixes regression introduced in r367349 which effectively resulted in truncation of quirk table.
