>Number: 5435
>Category: kern
>Synopsis: not probed old Gateway Communications LAN board
>Confidential: no
>Severity: non-critical
>Priority: medium
>Responsible: freebsd-bugs
>State: open
>Class: change-request

>Originator: Chiharu Shibata
>Organization:
Japan FreeBSD Users Group
>Release: FreeBSD 2.2.1-RELEASE i386 or later
>Environment:
G/Ethernet 16 Combo(ISA-LAN) by Gateway Communications,Inc.
>Description:
fe driver does not probe G/Ethernet 16 Combo, which has
FUJITSU MB86960A chip on the board.
Hardware specification is as follows.
IRQ : 3,4,5,6,7,10,11,12,15,2/9
I/O Address : 220-23F, 260-27F, 280-29F, 2A0-2BF, 2C0-2DF,
2E0-2FF, 300-31F, 320-33F, 340-35F, 360-37F,
380-39F, 3A0-3BF, 3C0-3DF, 3E0-3FF
>How-To-Repeat:
Just set the G/Ethernet 16 Combo, and boot.
>Fix:
The SRAM size is obscure. But 16KB specified by original
source causes errors "fe0:emptying receive buffer" and
"fe0:received a big packet?(XXXXX bytes)".
The following patch(based on 2.2.1-Release) specifies 8KB
for the safety, it seems to work well.
