Hi Adrian!

Thanks for looking into this!

Yes, it might very well be an ACPI-issue. I noticed the kernel is not completely locked up when I boot 16.0-CURRENT. If I do a verbose boot and press the power button (at the point where the system has stopped booting) another message appears on the console:

AcpiOsExecute: task queue not started

Every time I press the power button this line gets repeated.

I'm not sure if this is helpful in providing info about the hardware in this laptop but I installed 14.0-RELEASE on it so I could run pciconf -l -v, devinfo -r -v and do a verbose boot.

If you need more info, just let me know.
And if there is anything I can do so you don't have to get one of these laptops let know too.

The output of the commands seems a bit much to include in this mail so they're at pastebin:
devinfo: https://pastebin.com/6svCYbCF
pciconf: https://pastebin.com/N2TJKHLx

Kind regards!

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. ;-)

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. But today experimenting with 14.3-RELEASE and 15.0-STABLE
from 20251113 I got the same results.

It would be great to find a fix for this and would like to help
troubleshooting this issue. I'm not even close to a kernel developer
though, but perfectly capable of gathering all kinds of information (I'm
a FreeBSD-user since version 4.4) and help testing.
====

This is what I posted on the FreeBSD forum. The post is here:
https://forums.freebsd.org/threads/hp-probook-6550b-not-booting-14-3-release-15-0-stable.100065/

The conclusion there was to try again on this mailing list.

I tried kernels 14.1-RELEASE, 14.3-RELEASE, 15.0-STABLE and the most
recent version I tested with is
FreeBSD-16.0-CURRENT-amd64-20251110-dbb34d496708-281771
The problem is still there. It seems the system locks up since scolling
back up doesn't work either.

I wonder if anyone is willing to look into this. The offer to help
troubleshooting this and test a solution (if any) stands.

Kind regards,
Michael
