[issue1591] Lenovo X301 hangs with AHCI Driver CMD TIMEOUT STS=d0<BSY>

[Matthew Dillon]

:I just notice I got this else where in dmesg:
:
:----------
:
:**WARNING** waiting for the following device to finish configuring:
:xpt: func =3D 0xc015df7d arg =3D 0
:
:Giving up, interrupt routing is porbaby hosed
:
:-----------
:
:I believe this bug may well lie in the CAM XPT (transport) module, ie ATAPI=
:CAM?
:Looking for pointers to help me better trace down this problem please?
:
:Thanks,
:Edward.

    Usually this means a driver (probably the AHCI driver) has not finished
    the BUS SCAN.  The AHCI driver should complete it after the command
    times out.

    Tracking down why the command timed out in the AHCI driver is another
    issue entirely.  I don't have a quick answer.
