Can anyone already had a similar problem ? You can try to use reboot=pci as kernel parameter, I'm having similar (but intermittent) problems on an ASRock Q1900DC-ITX where this seems to help (but it's a bit too early to be sure about it, so a bit too early to submit the according kernel quirk).

Problem with ACPI on reboot
Hello evryone, I'm not sure that is the best mailing list to expose my problem, but I try anyway I've bought recently, an motherboard in order to make a simple server in my home, the model is a ASROCK Q2900 ITX (see documentation below) http://www.asrock.com/mb/Intel/Q2900-ITX/ My problem occur when I reboot the MB.

During my test, I've try to put acpi=off option to kernel and the reboot problem disappear, but this time it's the shutdown process which is impacted. When I type shutdown the system succesfully halt but the MB doesn't physically poweroff Can anyone already had a similar problem ? Thanks Pierre GINDRAUD Informatic french student pgindr...@gmail.com

I had very similar problem with my intel D2500CC board (also mini-itx), and before with similar (also intel) boards with prev-gen Atom CPUs. In all these cases the prob was a bug in bios and were fixed by updating the bios. Intel had a fix for prev-gen atom and the same bug on D2500CC which they fixed later, so I had to live with reboot probs for a while. In my case the bug was possible to work around by creating an ms-dos bootable partition on the hdd. That all to say: the chances are very high that this is a prob in bios. There's still a small chance that it is in linux (in kernel in this case), but if that's the case, debugging it will be quite difficult.

Re: Problem with ACPI on reboot
Thanks for your experience What do you mean by 'creating a msdos partition' ? Do you advice me to use the msdos partition table on the system disk and use a separated /boot partition for grub installer ?
