Cannot mount media in DVD rom drive, Acer Timeline 4810TG.

[Adam Niedling]

This is the reopening of bug #412527 for Natty.
There is a DVD eject button on these laptops, if they're pressed the drive is ejected but the DVD won't be mounted after insertion. However the "eject cdrom" command works.
Further info in the previously mentioned bug.

WORKAROUND #1: (should always work)
Instead of pressing the hardware button enter this command in the command line: eject cdrom

WORKAROUND #2: (works for some people including me)
In the BIOS set SATA mode from AHCI to IDE.

WORKAROUND #3: (works for some people but not for me)
Use the noacpi kernel parameter the following way:

1) sudo gedit /etc/default/grub
2) change the line
           GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to the following
           GRUB_CMDLINE_LINUX_DEFAULT="quiet splash noacpi"
3) save
4) sudo update-grub
5) restart the system

[Adam Niedling (krychek)]

Still an issue in Oneiric.

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest upstream kernel? It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the release candidate kernel versus the daily build. Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

[Adam Niedling (krychek)]

I tested it with upstream Linux 3.1 and it's still the same. (http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.1-oneiric/linux-image-3.1.0-030100-generic_3.1.0-030100.201110241006_i386.deb )

Is there any other way I can help?

[Joseph Salisbury (jsalisbury)]

This issue appears to be an upstream bug, since you tested the latest upstream kernel. Would it be possible for you to open an upstream bug report at bugzilla.kernel.org [1]? That will allow the upstream Developers to examine the issue, and may provide a quicker resolution to the bug.

If you are comfortable with opening a bug upstream, It would be great if you can report back the upstream bug number in this bug report. That will allow us to link this bug to the upstream report.

The bugzilla.kernel.org site may still be unavailable due to the recent break-in. If that is the case, please add the tag: kernel-needs-upstream-bug-report

Joseph: Could you help me with opening an upstream bug? Which Product/Component do I have to choose?
The same question goes for bug #811466. Thanks!

[penalvch (penalvch)]

Adam Niedling, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue in a supported release? If so, as per http://us.acer.com/ac/en/US/content/drivers an update is available for your BIOS (1.35). If you update to this following https://help.ubuntu.com/community/BiosUpdate , does it change anything?

If not, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful.

For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette .

If reproducible, could you also please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

In addition, could you please test the latest upstream kernel available (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-v3.12

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. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

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.

[Po-Hsu Lin (cypressyew)]

Closing this bug with Won't fix as this kernel / release is no longer supported.
Please feel free to open a new bug report if you're still experiencing this on a newer release (Bionic 18.04.3 / Disco 19.04)
Thanks!
