https://bugzilla.kernel.org/show_bug.cgi?id=43211 Summary: Pressing the DVD eject button renders the DVD-ROM unusable Product: IO/Storage Version: 2.5 Kernel Version: 3.2.0-24-generic Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: IDE AssignedTo: io_ide@xxxxxxxxxxxxxxxxxxxx ReportedBy: kricsek@xxxxxxxxx Regression: No Created an attachment (id=73209) --> (https://bugzilla.kernel.org/attachment.cgi?id=73209) sudo lspci -vvnn 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. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
