>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<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> 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 <full-duplex>)
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)
