https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D270707 --- Comment #35 from Matthias Lanter <freebsd@lanter-it.ch> --- The computer starts when hint.uart.1.at is commented out in the device.hint= s as described here: https://bugs.freebsd.org/bugzilla//show_bug.cgi?id=3D276011#c8 Unfortunately, the internal and external keyboards do not work in this way either. Since there were also such problems with the keyboard and trackpad under Li= nux and these have now been resolved, I looked into this a little: https://bugzilla.kernel.org/show_bug.cgi?id=3D216804#c18 The comment in the code: "IRQ override isn't needed on modern AMD Zen syste= ms and this override breaks active low IRQs on AMD Ryzen 6000 and newer systems. S= kip it." Could it be that it has something to do with that? Is there anything simila= r in FreeBSD? --=20 You are receiving this mail because: You are the assignee for the bug.=
