[-- Attachment #1 --] hi! The observation in the post about it being ACPI is also very valid. Can you share more specific details about the hardware in the laptop? It looks like I can pick one up cheap on ebay, and if it's an ACPI problem i'm likely going to need to add printf debugging everywhere to give the ACPI maintainer some more information. ;-) -adrian On Tue, 18 Nov 2025 at 11:21, Michael <opensource@uitveenendaal.nl> wrote: > Hello, > > ==== > One of my old laptops (HP ProBook 6550b) was running FreeBSD > 14.0-RELEASE (amd64) perfectly fine, but upgrading to anything higher > results in a boot that hangs at the line: > psm0: model Synaptics Touchpad, device ID 0 > > A while ago I tried upgrading to 14.1-RELEASE and run into this problem. > Back then I decided to wait, hoping this glitch would be ironed out in a > later release.
