CPU: EV4 (21064) major=2 minor=0 OSF PAL rev: 0x100000002012e >Description: doing following on a 4.7R box: # /sbin/ifconfig rl0 2001:858:101::3 prefixlen 64 resulted in: fatal kernel trap: trap entry = 0x2 (memory management fault) a0 = 0x0 a1 = 0x1 a2 = 0xffffffffffffffff pc = 0x0 ra = 0xfffffc0000363f88 curproc = 0xfffffe001078b540 pid = 52311, comm = ifconfig panic: trap syncing disks... 7 done Uptime: 1d12h39m39s im sorry but i have no gdb in the kernel as its a production shellbox and i just wanted to enable IPv6 with upgrading to 4.7R. i have 4.7R running on a i386 workstation on the same subnet and same command worked there flawless with 2001:858:101::2. so it makes me think this is a 64bit/kernel problem on alpha. interesting thing here is that the autoconfig of the interface during bootup gives: # ifconfig rl0 rl0: flags=8843 mtu 1500 inet 62.116.11.3 netmask 0xfffffff8 broadcast 62.116.11.7 inet6 fe80::200:b4ff:feaa:a14c%rl0 prefixlen 64 scopeid 0x1 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ether 00:00:b4:aa:a1:4c media: Ethernet autoselect (100baseTX ) status: active so the interface itself seems to be able to talk inet6. >How-To-Repeat: didnt try but i guess "ifconfig" wo crash the box a second time. (cannot test as i have no test box running 4.7/alpha) >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
