>Description:
If I load ahci then I'm not able anymore to use the dvd device in my Sony Vaio laptop. But if I leave a dvd medium in the drive while booting then I get /dev/cd0. If I don't leave a medium in the drive, I have to wait about 10 seconds to get some error:

ahcich1: Timeout on slot 0
ahcich1: is 00000000 cs 00000000 ss 00000000 rs 00000001 tfd 50 serr 00000000
run_interrupt_driven_hooks: still waiting after 60 seconds for xpt_config
ahcich1: Timeout on slot 0
ahcich1: is 00000000 cs 00000000 ss 00000000 rs 00000001 tfd 50 serr 00000000


Without achci I have to load smb and ichsmb to get /dev/acd0.

Maybe this is of some help: http://patchwork.ozlabs.org/patch/48596/

The Linux kernel had a similar problem, the drive was dead as long as I didn't leave a medium in the drive while booting.
