I'm using Ubuntu 12.04 with a Acer 4810TG laptop. This laptop has a DVD eject
hardware button which renders the DVD-ROM device unusable when it's pressed.

The "eject cdrom" command works if the button hasn't been pressed. But after
it's been pressed it does not work anymore:

$ eject cdrom
eject: tried to use `/dev/scd0' as device name but it is no block device
eject: unable to find or open device for: `cdrom'

The system has to be restarted to make the DVD-ROM work again.

Please see the attached dmesg-before.txt and dmesg-after.txt to see what's
happening when that button is pressed.

Also please take a look at the original bug report on Launchpad:
https://bugs.launchpad.net/ubuntu/+source/eject/+bug/412527
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/811464

WORKAROUNDS:

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.
