[T40] probably kernel panic - bridge module

[ailas]

Model: ReadyNAS Ultra 2.
Steps: donwload kernel 2.6.37.6, netgearize, make all, menuconfig and choose module below, make modules, install to /lib, modprobe bridge

Code: Select all

    [*] Networking support —>
        Networking options —>
            <M> 802.1d Ethernet Bridging


After modprobe bridge system stop responding. Probably kernel panic.
- System is dead by modprobe and doesn't react on double-push power button (which normally shutdown ReadyNAS Ultra 2).
- My delayed scripts to collect data in background are not executed.
- Nothing in logs (system, kernel, frontview, whole /var/log/...), tried "Download all logs" also. Just #restart mark after.

Can't test [T42], http://www.readynas.com/download/GPL/kernel-build-tools-x86-4.2.20-T42.tar.gz gives me NOT FOUND.

could you be able to send in your system logs zip file?

ilkevinli alias wasn't referring to the firmware image itself but rather the kernel build tools to use with it.

I can't help much with compling GPL code.

I can't help much with compling GPL code.

I could debug it myself, if i could flash my kernel into NAS with netconsole support.

Why didn't you just ask chirpa-san

Just posted 4.2.21-T7 beta, including the kernel sources.

[ailas]

Because I didn't get response on PM about NAT modules compiling which fails. I need VNP & NAT which is still not working so I'm going to sell my unit and build own. But I will try T7 with netconsole support before and send you logs if kernel panic happens.

I have over 500 unread PM's, sorry if one of those is you. I try to sort through them, but I don't get much time to hit the forums these days.

Now I tried the same again, as noted in my first post in this thread, with stable RAIDiator 4.2.21. Kernel 2.6.37.6.RNx86_64.2.4 #1 SMP on my ReadyNAS Ultra 2.

Download GPL, netgearized, make all... etc, to get same kernel as running in RAIDiator 4.2.21.
Now I still can compile USB sound modules as I desribed here - viewtopic.php?f=35&t=61970 modprobe, playing mp3 no problem here as before.

I even can compile bridge module as I described in first post in this thread. But the result is still the same.
KERNEL PANIC after modprobe.
And still CAN'T compile netconsole module to debug it across network.

ERROR: "netpoll_parse_options" [drivers/net/netconsole.ko] undefined!

Again, nothing in logs like before. (so it must be kernel panic). In all (system/kernel/etc) logs it looks like

Code: Select all

Jul  5 11:15:43 nas kernel: usbcore: registered new interface driver snd-usb-audio
Jul  5 11:38:56 nas syslogd 1.4.1#18: restart.


I modprobed usb sound and then compiled and modprobed bridge - panic. Restart in 11:38 is hard power reset.

Please, could you fix that? Kernel panic by bridge module, make netconsole module compilable or both.

"Netfilter connection tracking support" - NF_CONNTRACK can't be compiled as module too. So also support for fwknop (Single Packet Authorization and Port Knocking) is impossible.
