Hi Matthias, The C720 required special patches for the keyboard to work, which I originally added here: https://cgit.freebsd.org/src/commit/?id=6c176113bbdd598231ec47d161d4c3714997169b I assume that something in that area changed recently. Without digging into it, this looks like a possible cause: https://cgit.freebsd.org/src/commit/sys/dev/atkbdc/atkbd.c?id=ce881170088c4c98c036fe561f8ee8413c2e2585 atkbd: Disable periodic polling by default. It is one of the few remaining Giant-locked callouts. It would be good to remove it, not mentioning that polling itself is not good. If this cause keyboard/mouse freezes on some hardware, please set loader tunable hw.atkbd.hz=1 as workaround and report the issue. So you could try to set hw.atkbd.hz=1 (or hw.atkbd.hz=10) in /boot/loader.conf, then reboot and see if it helps. Best Michael -- Michael Gmelin
