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 Thinking I would be all cool and step through the crash dump I started up gdb only to realize I don't have gdb. However, I do have the kernel with debugging info and the crash dump (all 2GB!). I looked through the archives and it doesn't appear there is a FreeBSD Sparc64 gdb. Is there? If not, how do I help debug the crash dump? I really like FreeBSD and would like to do this using FreeBSD 5.2. Can someone throw me a bone? <> Jim I am also providing the following in case it's helpful: uname -a output: test60# uname -a FreeBSD test60 5.2-RELEASE FreeBSD 5.2-RELEASE #0: Wed Jan 28 14:59:57 EST 2004 root@test60:/usr/obj/usr/src/sys/MYKERN sparc64 dmesg: Copyright (c) 1992-2004 The FreeBSD Project.
