System: NetBSD endymion 1.5.1 NetBSD 1.5.1 (endymion) #3: Thu Jul 26 02:16:02 CEST 2001 jb@endymion:/usr/src/sys/arch/i386/compile/endymion i386


>Description:
	Booting the kernel on my laptop (compaq armada 7360) when it
	is plugged on its docking station results in the following
	panic message : 
isa1 at pcib1panic: isaattach: ISA bus already seen!
>How-To-Repeat:
	I have no clue if this problem is reproductible with other
	laptops. Simply boot the generic laptop kernel on the machine
	when it is plugged on the dock station.
>Fix:
	The following works :

	/sys/arch/i386/pci/pcib.c :
	---------------------------------
	[...]
	void
	pcib_callback(self)
	        struct device *self;
	{
	        struct isabus_attach_args iba;
	        extern int isa_has_been_seen;
	
	        if (isa_has_been_seen == 0) {
	                /*
	                 * Attach the ISA bus behind this bridge.
	                 */
	                memset(&iba, 0, sizeof(iba));
	                iba.iba_busname = "isa";
	                iba.iba_iot = I386_BUS_SPACE_IO;
	                iba.iba_memt = I386_BUS_SPACE_MEM;
	#if NISA > 0
	                iba.iba_dmat = &isa_bus_dma_tag;
	#endif
	                config_found(self, &iba, pcib_print);
	        }
	}
	[...]
	----------------------------------

	but is maybe unsatisfactory (suggested by Aymeric Vincent).
