https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D249987 Bug ID: 249987 Summary: Lenovo X120e touchpad failing Product: Base System Version: 12.1-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: jwb@freebsd.org Since a few months ago, /dev/psm0 sometimes does not get created on boot and sometimes disappears after boot, often after a suspend/resume cycle. The o= nly workaround I've found is to power off the machine and restart, which brings back touchpad functionality only sometimes. I did fresh 12.2-BETA3 install before filing a PR to see if the issue may = have been resolved, but it has not and in fact a new issue has appeared: Tapping= no longer works as a left-button click. I've added hw.psm.mux_disabled=3D1 per syslog suggestion and will report ba= ck after a testing period once I know if it helped. Data from 12-2-BETA3: dmesg: kbd0 at atkbd0 atkbd0: [GIANT-LOCKED] psm0: <PS/2 Mouse> irq 12 on atkbdc0 psm0: [GIANT-LOCKED] psm0: model Synaptics Touchpad, device ID 0 dmidecode: Handle 0x0005, DMI type 8, 9 bytes Port Connector Information Internal Reference Designator: J1900 Internal Connector Type: None External Reference Designator: Touch Pad External Connector Type: PS/2 Port Type: Mouse Port /var/log/messages: Sep 28 20:16:55 quagga kernel: psm0: <PS/2 Mouse> irq 12 on atkbdc0 Sep 28 20:16:55 quagga kernel: psm0: [GIANT-LOCKED] Sep 28 20:16:55 quagga kernel: psm0: model Synaptics Touchpad, device ID 0 Sep 28 20:26:32 quagga kernel: psm0: AUX MUX hang detected!
