>Description:
Cannot use my DVD device when I set my BIOS interface to ahci (HP Probook 4510s), it seems to timeout as you can see with mplayer :

   libdvdread: Get key for /VIDEO_TS/VIDEO_TS.VOB at 0x00000150
   libdvdread: Error cracking CSS key for /VIDEO_TS/VIDEO_TS.VOB (0x00000150)
   libdvdread: Elapsed time 10

(in dmesg)
   acd0: FAILURE - SEND_KEY timed out
   acd0: FAILURE - SEND_KEY timed out
   acd0: FAILURE - SEND_KEY timed out

I sent an email to freebsd-stable@

http://lists.freebsd.org/pipermail/freebsd-stable/2010-May/056697.html
>How-To-Repeat:
Set the interface to ahci (and not ide) on a HP Probook 4510s and try anything related to the dvd device.
>Fix:
For the moment for HP Probook users, go to the BIOS and switch from AHCI to IDE interface.

 Hi.
 
 Please retry on fresh 8-STABLE. Many things have changed.
 
 Also looking on acd0 device names in dmesg I have doubts that you are
 really using ahci(4) and not legacy ataahci from ata(4).
