Hi,
I hit the following panic on my gateway (amd64 -current), after a
snapshot upgrade.
It isn't a regression from directly previous version as I rollback to it
and trigger the panic again.
The panic occurs at boottime, at network configure (netstart).
> starting network
> add net default: gateway 0.0.0.1
> add net default: gateway fe80::
> panic: pool_do_get: mbufpl free list modified: page 0xffffff002f990000; item
> addr 0xffffff002f990000; offset 0x8=0x10
It is due to my /etc/hostname.pppoe0
--- BEGIN /etc/hostname.pppoe0 ---
down
inet 0.0.0.0 255.255.255.255 NONE \
pppoedev vlan10 authproto pap \
authname 'xxx' authkey 'xxx' \
up
dest 0.0.0.1
inet6 eui64
description "Internet output"
group internet
!/sbin/route add -inet default -ifp pppoe0 0.0.0.1
!/sbin/route add -inet6 default -ifp pppoe0 fe80::
--- END /etc/hostname.pppoe0 ---
Removing the last line (route add -inet6 default ...) remove the panic
and running the command later make no problem (and my ipv6 is
functionnal).
I am able to fully repeat the panic on demand (but it is my gw, don't
ask too often :) )
Next it output from savecore.
dmesg + ps
