ahci: attachment to atapi device

[Matthew Dillon]

:ahci0.0: CMD TIMEOUT state=5 slot=22
:        cmd-reg 0x4d617<HPcP,CR,FR,FRE,POD,SUD,ST>
:        sactive=004000000 active=00000000 expired=00000000
:           sact=000000000     ci=00000000
:ahci0.0: disk_rw: timeout

    Are you absolutely sure these TIMEOUT's are coming from ahci0.0 ?

:I then tried again after unpluging the burner:
:...
:
:[...]
:mountroot> ufs:da0s1a
:Mounting root from ufs:da0s1a
:cd0 at ahci0 bus 1 target 0 lun 0

:cd0: 150.000MB/s transfers
:cd0: Attempt to query device size failed: NOT READY, Medium not present - tray
:closed

    Wait, you said you unplugged the burner.  Why is still being probed?
    Do you have multiple CD/DVD drives?  Make sure they are all unplugged.

:It ends with these two lines:
:da0: reading primary partition table: error accessing offset 000000000000 for 512
:Root mount failed: 5

:Here you go:

    NATA is probing them at 3 GBits, so that probably isn't the problem.
    Stil, I added a feature to the driver to force 150, add this to your
    loader.conf or set from the boot loader:

	set hint.ahci.force150

    Ok, I'd like you to sync the git repo again, I added some additional
    output to the TIMEOUT message.

    You don't have to type everything in again :-), but please tell me what
    the STS line in the CMD TIMEOUT message says (that I just added to the
    driver code).
