Mark Edgington, could you please test the latest upstream kernel available from
the very top line at the top of the page (not the daily folder) following
https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional
upstream developers to examine the issue. Once you've tested the upstream
kernel, please comment on which kernel version specifically you tested. If this
bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER
where VERSION-NUMBER is the version number of the kernel you tested. For
example:
kernel-fixed-upstream-3.16-rc5
This can be done by clicking on the yellow circle with a black pencil
icon next to the word Tags located at the bottom of the bug description.
If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER
Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.
** Tags added: latest-bios-a04
** Description changed:
- On a Dell Inspiron 1210 ("Mini 12"), the power-button is not recognized
- with recent kernel versions. I know it *is* recognized with the linux-
- image-3.11.0-23-generic kernel (I did not test out several images to
- determine exactly where the regression/bug was introduced). The BIOS of
- the Inspiron is version A04 (the latest version available).
+ On a Dell Inspiron 1210 the power-button is not recognized with recent
+ kernel versions. I know it is recognized with the linux-
+ image-3.11.0-23-generic kernel.
To reproduce:
-
1. boot normally with a "bad" kernel version (e.g. 3.13.0-32-generic, as
provided in Ubuntu where the kernel is configured with the CONFIG_ACPI_BUTTON=y
option)
2. switch to a console and log-in (or alternatively, open a terminal after
logging in to a desktop env.)
3. run the "acpi_listen" executable from the terminal
4. press the power button.
-
- With a "bad" kernel version, nothing will happen (no text will be
- printed to the screen). With a "good" version, you will see some text
- indicating that an event occurred.
-
- Consequently, with a "bad" kernel, if you suspend the machine via the
- power-off menu option, there is no way to resume (I also tried to close
- and open the lid after suspending, to no avail).
