It works most of the time (where the 0.5 didn't work most of the  
time), but I still see the "Badness in __msleep" occasionally (and it  
only detects one of the disks then).    However, the Adaptec BIOS is  
only seeing one of the disks sometimes, so maybe there's something  
wrong with the hardware.  The BIOS did detect both drives in the boot  
that gave the output below though.
