[Bug 412527] Re: Cannot mount media in DVD rom drive, Acer Timeline 4810T. Drive is detected, and media only detected if placed in the drive when machine suspended. Even then DVD movies (purchased) are not recognised - error message that media is unknown. Audio cd's sometimes play. When trying to unmount, I am asked for my password - message given that another user mounted the media.

I just booted and startet "lshw" |grep MATSHITA:

dmesg output:

[ 68.680024] ata6: failed to reset engine (errno=-5)
[ 72.844097] ata6: softreset failed (device not ready)
[ 72.844104] ata6: hard resetting link
[ 77.320096] wlan0: no IPv6 routers present
[ 78.704047] ata6: failed to reset engine (errno=-5)
[ 83.908097] ata6: link is slow to respond, please be patient (ready=0)
[ 107.896232] ata6: softreset failed (device not ready)
[ 107.896242] ata6: limiting SATA link speed to 1.5 Gbps
[ 107.896246] ata6: hard resetting link
[ 113.424257] ata6: failed to reset engine (errno=-5)

My drive is a :

Host: scsi5 Channel: 00 Id: 00 Lun: 00
  Vendor: MATSHITA Model: DVD-RAM UJ892AS Rev: 1.00
  Type: CD-ROM ANSI SCSI revision: 05

on a new notebook:

Acer TravelMate TM8571-352G25Mn

I can only eject discs with the "eject" command, which works fine:

If I press the eject button on the keyboard, the operating system hangs for some seconds, till the eject
is done !

The dmesg output is then:
[ 556.808241] atkbd.c: Unknown key pressed (translated set 2, code 0x91 on isa0060/serio0).
[ 556.808249] atkbd.c: Use 'setkeycodes e011 <keycode>' to make it known.
[ 556.818988] atkbd.c: Unknown key released (translated set 2, code 0x91 on isa0060/serio0).
[ 556.818995] atkbd.c: Use 'setkeycodes e011 <keycode>' to make it known.
[ 568.644261] ata6: SATA link up 1.5 Gbps (SStatus 113 SControl 310)

and further discs are not recognized anymore !

Following some hints changing SATA Mode from AHCI to IDE does not work for me,
because then the Matshita drive is not detected any more, even in the BIOS !
