>Description:
	After resuming the system with a kernel built after the MFC of the
ATA driver, when the ATA devices are reset, what was once a ATA100
device, now is seen by the system as ATA33.
>How-To-Repeat:
	Well.. I have not had a chance to reproduce the problem on any other
machines, as this is my only FreeBSD laptop.  But, I will be able to
provide all access neccessary to find what is causing this problem.
>Fix:

	Unknown at this time.
