>Release:        FreeBSD 5.0-20001114-CURRENT i386
>Organization:
>Environment:

	software -- 5.0-20001114-CURRENT
	maybe ealier but after 200006xx. The previous version used
	is 200006xx which is OK for ep0.

	hardware -- AMD K6-II 500MHz with ASUS P5A-B motherboard +
	3c509 Ethernet adapter.

>Description:

	If irq for 3c509 board is set to 15, the board will not be configured,
	and system will boot with ep0 (but some ti{0-1} are up).

	If irq for 3c509 board is set to non-15, and ie0, fe0, le0, cs0,
	lnc0 and sn0 are enabled, system will hang as soon as it detects
	the ep0. This has been a problem for long long time.

	If irq for 3c509 board is set to non-15, and ie0, fe0, le0, cs0,
	lnc0 and sn0 are disabled; or set 3c509 board to PNP, system will
	panic, once the ep0 is configured.

>How-To-Repeat:

	Boot installation floppies and may sure to set 3c509 able to be
	configured, then it wil panic.

>Fix:
