>Release:        FreeBSD 2.2.1-RELEASE i386
>Environment:

	Booting default (install) kernel on Pentium with SMC Ultra Elite
	configured at 0x240, IRQ 11, memory address C8000; kernel
	defaults are 0x280, IRQ 5, memory address D8000.

>Description:

	The specified configuration causes a kernel panic as soon
	as the kernel editor is used to change the I/O and IRQ addresses
	to match the the card (not that in 2.2.1, the buffer address
	cannot be edited.  A distinct PR has been filed on this 
	omission.)

>How-To-Repeat:

	Boot as specified above, watch the crash.

>Fix:
	
	Unknown.
