I am interested in using FreeBSD 5.2 on an Ultra 60 with a PCI qfe card. I
want to use the bridging and dummynet functionality.
I installed FreeBSD 5.2 with not problems. I added options BRIDGE to a
custom kernel conf file and rebuilt/installed the kernel according to
procedure 1 at:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig-build
ing.html
I then reboot and do the following:
test60# sysctl -w net.link.ether.bridge.enable=1
net.link.ether.bridge.enable: 0 -> 1
test60# ifconfig hme1 up
test60# ifconfig -a
hme0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 192.168.234.208 netmask 0xffffff00 broadcast 192.168.234.255
inet6 fe80::a00:20ff:fe9a:e692%hme0 prefixlen 64 scopeid 0x1
ether 08:00:20:9a:e6:92
media: Ethernet autoselect (100baseTX)
status: active
hme1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet6 fe80::a00:20ff:fe9a:e692%hme1 prefixlen 64 scopeid 0x2
ether 08:00:20:9a:e6:92
media: Ethernet autoselect (100baseTX <full-duplex>)
status: active
(rest cut...)
test60# sysctl -w net.link.ether.bridge.config=hme0,hme1
net.link.ether.bridge.config: -> hme0,hme1
Consistently within a few seconds I see the following while watching on
Serial Port A:
FreeBSD/sparc64 (test60) (ttya)
login: Jan 28 15:28:58 test60 kernel: hme0: promiscuous mode enabled
Jan 28 15:28:58 test60 kernel: hme1: promiscuous mode enabled
panic: trap: memory address not aligned
cpuid = 0;
syncing disks, buffers remaining... 563 563 563 563 563 563 563 563 563 563
563 563 563 563 563 563 563 563 563 563
giving up on 455 buffers
So I thought instead of blindly asking for help I'd try to provide more
useful information. I read the following articles on kernel debugging:
http://www.onlamp.com/pub/a/bsd/2002/03/21/Big_Scary_Daemons.html
http://www.onlamp.com/pub/a/bsd/2002/04/04/Big_Scary_Daemons.html
So:
test60# ./gdb53 -k kernel.debug vmcore.0

So I'm hoping this helps. What is the next step? Can I provide more
information? I would be happy to try fixes.
I would appreciate any help someone could offer.
Thanks,

I am also providing the following in case it's helpful:
