https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D240339 Greg V <greg@unrelenting.technology> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|New |Closed Resolution|--- |Not A Bug --- Comment #12 from Greg V <greg@unrelenting.technology> --- I think I found the culprit, it's the length retrieval in get_input_report.= I changed it to just trust the given length =E2=80=94 touchscreen works, touc= hpad doesn't receive evdev events yet (hmm) but doesn't crash the controller and I can s= ee the reports changing with a debug print, and reload the module multiple tim= es. Seems like ig4 is innocent and it's the touchpad firmware reacting to iichid that's causing the bus to get screwed up.
