System: NetBSD sopwith.uucp 1.6.2 NetBSD 1.6.2 (ALPHA-$Revision: 1.4 $) #11: Tue Jun 29 12:05:05 PDT 2004 root@sopwith.uucp:/usr/src/sys/arch/alpha/compile/SOPWITH alpha
Architecture: alpha
Machine: alpha
>Description:
	Multiple tulip boards, using the tlp driver, attempt to share an interrupt,
and don't work.

See:
	http://mail-index.NetBSD.org/netbsd-help/2004/05/18/0006.html
	http://mail-index.NetBSD.org/netbsd-help/2004/05/19/0006.html
	http://mail-index.NetBSD.org/netbsd-help/2004/05/21/0001.html
	http://mail-index.NetBSD.org/netbsd-help/2004/05/21/0002.html

>How-To-Repeat:
	Plug in 2 tulip boards, use the tlp driver, observe that only one works,
presumably because they are attempting to share an interrupt.
>Fix:

workaround #1:

	The fix in http://mail-index.NetBSD.org/netbsd-help/2004/05/19/0006.html
works for me, however note that Manuel Bouyer says it will break multi-port boards.

workaround #2:

	I did get the de driver working, by hard coding the media type
in /etc/rc.conf.  However, I get the impression that the de driver may go
away someday?

 Something like the following would at least be an improvement, though it 
 wouldn't fix the problem in all cases.

 If someone has one of the Cogent boards, could you set tlp_srom_debug and 
 email me the output?

 Whatever the problem, it's not all instances of two Tulip boards; I've 
 been running this way for about a year on 1.6.x:

 $ dmesg|egrep tlp
 tlp0 at pci0 dev 9 function 0: ADMtek AN985 Ethernet, pass 1.1
 tlp0: interrupting at irq 10
 tlp0: Ethernet address 00:0c:41:22:cc:01
 ukphy0 at tlp0 phy 1: Generic IEEE 802.3u media interface
 tlp1 at pci0 dev 11 function 0: ADMtek AN985 Ethernet, pass 1.1
 tlp1: interrupting at irq 12
