kernel 3.13.6 ACPI shutdown does not work
This seems a regression. Could you do a bisect between v3.11.10 and v3.13.6 to find out which commit cause this issue? According to bisect output the first bad commit is: [1696d9dc57e062ce5200f6a42a6aaada15b434bb] ACPI: Remove the old /proc/acpi/event interface Full log from bisect is in the attachments.

button.patch
Please try this patch and attach the ACPI power button event file. It's /etc/acpi1/events/powerbtn on my ubuntu machine.
@Lan Thanks for the patch. I applied it to v3.13.6 stable and it solves the issue, i.e. ACPI shutdown button works again. I attache my powerbtn handler as well, but I guess it is no longer relevant. Also I am running pure server config, no X subsystem is present, so while the handler is quite convoluted, I guess only the last line applies in my case. Created attachment 129371 [details]
power button event handler (gentoo x64)
Thanks for test. I will upstream the patch soon. Patch has sent to ACPI maillist. https://patchwork.kernel.org/patch/3838071/ |
Created attachment 128601 [details] kernel 3.13.6 ACPI shutdown does not work I have been running gentoo x64 guest in Windows 7 x64 VirtualBox host for some time. There is an option to execute ACPI shutdown of the guest directly from VirtualBox console window menu. Note: I am running vanilla kernel in gentoo (i.e. no gentoo patches). This was working until kernel version 3.11 included (right now I am at 3.11.10, but it worked on all versions before). After upgrading to kernel 3.12 (and eventually 3.13) I noticed I can no longer ACPI shutdown the guest. It looks like the event is ignored. (I have tried with and without VirtualBox extensions, it does not matter). I got ACPI traces from working kernel (3.11.10) and non-working kernel (3.13.6) which I include in the attachment. As suggested by the trace it seems that in v3.13.6 GPE00 register is disabled. In v3.11.10 the same register in enabled. I tried to reenable GPE00 in v3.13.6 by: echo "enable" > /sys/firmware/acpi/interrupts/gpe00 but while it shows the register GPE00 after this as "enabled" it does not help the shutdown to succeed.
