#3868 assigned bug
Hang on shutdown/reboot (synaptics related?)

Description
My laptop hangs on shutdown/reboot, if acpi is not enabled. The last thing I see on screen is "Waiting for other processes to quit", then it hangs there. No "reboot now". With ACPI Enabled, instead, it displays the "reboot now" button (it should shutdown or reboot automatically, but this should be a different bug, I guess). This started happening only since some time (a month or so).
The laptop is a Fujitsu Siemens amilo LI2735, centrino based. hrev30622.

The problematic change should be the one from Olivier which kills all apps before rebooting. Obviously, there is one (or more) components in your system that doesn't like to be freed.
Can you remove drivers to find the candidate?

Yeah, that's what I was thinking, too. It's weird it doesn't happen with ACPI enabled, though.
Can you remove drivers to find the candidate?
Yes, of course. Will do that this evening.

False alarm, though my initial comment still applies that I had the hang described with ACPI enabled. Perhaps accidentially.
Just tested:
- with ACPI: reboot fine
- w/o ACPI: reboot fine
Sorry for disrupting.

Tried removing hda (audio), rtl82xx (network) and the problem is still there. Will try removing more stuff.

Looks like the problematic driver is the touchpad one. If I comment out the whole synaptics_close() implementation, the laptop reboots correctly. Now I'll try to find what exactly hangs.

That's not even too surprising considering that the reboot is usually triggered via the keyboard controller. Eventually, the driver needs to reset the controller when it's closed.

have the same problem, haven't tried messing with acpi
as a temporary fix you can use shut down and then power on manually, that doesn't seem to be a problem

Can you recheck this with a recent Haiku build? It may have been fixed recently.

I have two separate machines that fail to shutdown with r1a3 still. They are both laptops with trackpads, so I have a feeling they're both related to jackburton's comment:7
I haven't had time to test that hypothesis.

Still with us in alpha4.1. Any advice on how to debug this, given that I can't enter KDL when the machine is freezed?

Replying to korli:
No serial output on this laptop?
Nope. I guess I could get an USB-Serial converter where I work, and another pc with a serial port to interact with it, but is it supported ?

Things like these are pretty hard to debug. I would try to remove as much drivers as possible (including legacy things like PS/2), and see if the problem persists. But even if you manage to identify the one driver causing the problem (if there is any), it may not actually cause it :-)
Well, good luck, anyway :)
I had a hard time trying to debug a similar issue on my old SiS 630 based laptop. In the end I think the problem could only be avoided by a very particular shutdown sequence (concerning when to turn off interrupts, and how to talk to the keyboard controller to do the reset).

With recent revisions, the problem has changed a bit: I now get a KDL on shutdown (seems related to ACPI). Should I change the ticket description or should I open a new one ?

Not sure if this one should be closed.

hrev52017 tested. This is on specific hardware (I haven't reproduced it on any test hardware yet, but known issue on a user's (vidrec) Dell-related system (but shutdown works on his other test system). I've seen it happen on Win/Linux/BSD so not Haiku-specific in nature. If any process hangs, I usually kill it in the dialog box or go back to review apps/processes which require 'kill team' tactics.
I can 'suggest to closing this ticket' and tracking on the wiki on 'specific hardware' with this issue - to consolidate and isolate.
Can confirm this. Happened yesterday with ACPI enabled. Can't recall if it always happens as my system usually freezes during operation and I regularly don't restart ;)
