Computer reboots when asked to shut down in Feisty

[Alexander Jones]

Binary package hint: acpi-support

When asking my computer to shut down, instead of powering off at the end of the procedure, it restarts.

What is strange is that the power seems to be momentarily cut for a split second - you can see the lights on my computer dim and the fans temporarily power down for a tiny fraction of a second before it starts back up again. This, incidentally, is the same as what happens when I ask this computer to Suspend to RAM.

Though the Suspend-to-RAM behaviour has been present for as long as I can remember (at least as far back as Edgy), this shutdown misbehaviour is new to Feisty.

Alex, please update the bug report with the output of

uname -a

Also, please run the following commands and attach their output to the report, one attachment per command:

sudo lspci -vv

sudo lspci -vvn

sudo dmidecode

Please be sure to attach as there will be a lot of output. Also please be sure to run with sudo, as these commands require root access to get to the required information.

For the suspend-to-RAM problem, it may also be useful to run

lshal -m

suspend, get back to your session, then attach the output of the command. (I'm assuming suspend-to-ram blinks lights and returns, and doesn't reboot... ...if it does reboot, ignore the lshal request, it won't be useful.)

Thanks!

I will deal with the suspend-to-RAM thing in a different bug, but I will do what you said.

FTR, it doesn't reboot when asked to suspend, it just instantly resumes.

Thanks!

Confirmed based on availability of requested logs.

With acpi=off passed to kernel, machine halts properly on shutdown, though it does not turn itself off.

I confirm the bug. I'm using an Acer Aspire 1692 laptop, and here is my info:

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this bug to the new "linux" package. However, development has already began for the upcoming Intrepid Ibex 8.10 release. It would be helpful if you could test the upcoming release and verify if this is still an issue - http://www.ubuntu.com/testing . If the issue still exists, please update this report by changing the Status of the "linux" task from "Incomplete" to "New". We appreciate your patience and understanding as we make this transition. Thanks!
