Please try current trunk, please also mention the exact firmware revision whenever you report an issue.

comment:2 Changed 3 years ago by christian@…

image build from r44843

comment:3 Changed 3 years ago by anonymous

not fixed in r44945 tested with archer-c5v1

comment:4 Changed 3 years ago by fclql

Did you solve this problem?

comment:5 Changed 3 years ago by christian@…

I'm still investigating.

But it seems, that r44974 without ebtables and with kernel 3.14 is stable [no oops] (in my setup with ipsec and batman).

In case somebody has similar issues please raise you hands...

comment:6 follow-up: Changed 3 years ago by nbd

is 3.18 stable without ebtables as well?

comment:7 in reply to: ↑ 6 Changed 3 years ago by fclql

Replying to nbd:

is 3.18 stable without ebtables as well?

ebtables doesn't matter same. use 3.14 kernel config configuration without error

comment:8 follow-up: Changed 3 years ago by nbd

please run another test with the latest version, then do the following:
post the output of ./scripts/diffconfig.sh, /etc/config/network, /etc/config/firewall, /etc/config/wireless and any other config files / modifications that might be relevant for reproducing the issue.
also, please *always* mention the revision number that you're using, and not just 'latest' - otherwise things become unnecessarily hard to keep track of.
