Description Jonathan Müller 2005-11-14 11:11:41 UTC
These Thinkpads cannot shutdown properly due to a bios error. This could also happen on other older notebooks.
To fix, set the option in "Power Management Options > APM Bios Support > Use real mode APM Bios call to power off" to YES.
Comment 1 Jonathan Müller 2005-11-14 11:13:27 UTC
After having shut down everything i shows the message:
proc umounted
The system will be halted immediately
after that the fan stops but it doesn't shut down.
Comment 2 Michael Gross 2005-11-14 15:24:35 UTC
As you already realized, those problems are coming from buggy BIOSes. Notebook BIOS's are especially buggy. I don't think we can do anything here.

Stefan: Can you please comment on that and decide what should be done?
Comment 3 Thorsten Kukuk 2005-11-14 21:21:33 UTC
I can only say: Works fine for me with default settings on my T22.
But you have to specify acpi=off on this machines, else it will of course not work.
Comment 4 Jonathan Müller 2005-11-14 21:38:03 UTC
I think making a new kernel available with this option set to yes would be the easiest solution because those who aren't developer's wouldn't find out about setting acpi=off...

This is wrong. It is well documented and if you don't specify acpi=off, most of the mini-PCI cards even don't work in a T2x. acpi=off is even a option in the install menu.



Comment 6 Stefan Behlert 2005-11-15 10:47:11 UTC
I don't see anything we can do here. I expect it might be fixed with a new BIOS, otherwise I don't see what we can do for you here.
Thomas, any idea regarding that problem? If not, I would suggest to close the bug.
Comment 7 Thomas Renninger 2005-11-15 12:26:11 UTC
You either hit bug: 
#113884  (In this case this bug is not only valid for Thinkpad A2x, but for more machines). If it works for you to disable the powersave daemon (chkconfig powersaved off -> reboot -> try to shutdown). Then please read the last comment there and try out my suggestions and mark this one as a duplicate of #113884.

or bug:
...Won't search now, this one is fixed. You can try out current kernel of the day from:
ftp.suse.com/pub/people/mantel/kotd/10.0-i386/SL100_BRANCH/kernel-default.i586.rpm
Please close the bug fixed it this kernel works for you, the change will be in the next upcoming YOU update kernel.
Comment 8 Jonathan Müller 2005-11-15 16:38:38 UTC
I'm really sorry. It works when disabling ACPI.
Comment 9 Jonathan Müller 2005-11-15 16:41:06 UTC
I'm changin it to fixed. What a pity the T2x don't support ACPI. Sorry for disturbing you
Comment 10 Thomas Renninger 2005-11-15 17:24:01 UTC
Have you disabled the powersave daemon or have you booted with acpi=off?

When you disabled the powersave daemon and it worked, it is bug #113884.

If this does not help you can try the kernel I pointed to in comment #7 or wait for the next YOU update kernel. Hopefully the fix added there helps.
Comment 11 Jonathan Müller 2005-11-16 17:29:45 UTC
Well, I booted with acpi=off and I haven't tried the kernel of comment#7 yet.
