G4 XServe hangs when hot swapping drives

[Chris Murphy]

Whenever removing these drives (drag icon to trash, wait, push  
handle, wait for drive to spin down, pull drive), shortly thereafter  
the machine is unresponsive. It's not possible to even ssh into the  
machine. This occurs the vast majority of the time, at least 8 in 10  
attempts.

To prepare them, they're inserted, and initialized using Disk  
Utility. The drives are Apple drives, in Apple sleds. We've gone  
through a dozen drives, and have used three different bays and the  
problem is the same.

Clearly the machine doesn't like what we're doing. Is there something  
else that should be done when hot swapping these drives?
