RT-N66u IPV6 constant rebooting

[psyc0ld]

Hi everyone

I was testing IPV6 on my RT-N66u with merlin's firmware 380.57 and now 380.58 but I have a strange behaviour with my router.
I first enable IPV6 with a native connection on the PPP interface and DHCP-PD enable. The router reboot fine, waiting for my wan connection to kick in but immediately the connection is done the router reboot. I did a test once and the router reboot for 30 min to get a stable connection.
I even did a factory reset with the same result.

Anyone else experiencing this behaviour?

Thanks

PS. First post here and I want to thank Merlin for his great works with this firmware.

Try disabling NAT acceleration under LAN -> Switch control.

It's already disable.
