And there are no messages about a disk drive being detected. It looks
as so:

[    2.652264] sd 0:0:0:0: [sda] 1464640512 512-byte hardware sectors (749896 MB)
[    2.652375] sd 0:0:0:0: [sda] Write Protect is off
[    2.652448] sd 0:0:0:0: [sda] Mode Sense: 06 00 00 00
[    2.652515] sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA
[    2.654013] sd 0:0:0:0: [sda] 1464640512 512-byte hardware sectors (749896 MB)

So somehow you either don't have the drive for it, or you are missing
the SCSI_WAIT option (not sure of the name).
