Can you attach any system logs?

I have found a similar problem but in my case I don't think it's related to ACPI. In fact the problem is still there after adding the kernel option acpi=off. @walter59, can you test on your system by disabling ACPI too?

During system shutdown, started by "shutdown -h now", the process hangs (but the system is still working) during stopping of samba service. Instead the reboot still works.

My problem appeared with the upgrade 6.5.11 -> 6.6-rc1 so I have bisected until I have found the first bad commit:

It is possible that

https://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs.git/commit/?h=vfs.fixes&id=796432efab1e372d404e7a71cc6891a53f105051

might address the Samba shutdown issue. Please give that a try.

I tried that commit on top of v6.6.2 and it works. So my issue has been solved!
