https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=260381 Bug ID: 260381 Summary: sysmouse or psm delays button release events by about 900ms Product: Base System Version: 12.2-STABLE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: firstname.lastname@example.org Since I updated an old laptop from 11.<something>-STABLE to 12.3-STABLE (built from revision d891ee6ac7e6af693959c6d11c5af7c440919ea9) the trackpad became unusable: whichever button is clicked, button up events are delayed by about 900ms or until another event is to be reported within that time window. As an illustration here is a trace of a single click, the first column is a timestamp, last three columns are the reported button states: 1639384474.857087 Buttons: d u u 1639384475.797024 Buttons: u u u Trace of a double click: 1639384495.480674 Buttons: d u u 1639384495.601411 Buttons: u u u 1639384495.649127 Buttons: d u u 1639384496.587823 Buttons: u u u At boot time the device is reported as psm0: <PS/2 Mouse> irq 12 on atkbdc0 psm0: [GIANT-LOCKED] WARNING: Device "psm" is Giant locked and may be deleted before FreeBSD 14.0. psm0: model Synaptics Touchpad, device ID 0 This looks to be a resurrection of bug #137228 (reported in 2009). [BTW, bugzilla lacks a 12.3-STABLE tags in the version number selector.] -- You are receiving this mail because: You are the assignee for the bug.
