I've noticed that sometimes probe messages from the ata subsystem
appears to come interspersed into other output during boot.

Notice how the first "satalink0: ..." line comes in the middle of
the probe message from cd0.
Anyone have any good idea how to fix this? Is this becuase there
are some sleepable operations done in-between the printing of the
different parts of the line containing "cd0: drive supports"?
Yes, this is somewhat cosmetic, I'll concede...
