Once I fixed another bug with de(4) due to ru@'s recent changes I wasn't able to reproduce an alignment trap with de(4) on my alpha, so although I have a patch for de(4) I can't test it. How are you triggering the alignment fault? Do you have something other than 'ifconfig_dc0="DHCP"' in /etc/rc.conf? -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.org
