Kernel Panic

eri--

That is for full install 32bits.
It should work even on alix boards i am not sure on others since i cannot build for those now.

It should fix all the panics in vr, em or other nics.

vito

Should we be using this snap and later?
pfSense-Full-Update-2.0-BETA5-i386-20110126-0422.tgz 26-Jan-2011 09:47 83M

eri--

Yes.

jnorell

Done.

hugo

Will there be an amd64 version of the fix?

LostInIgnorance

This is what I am supposed to do, correct?

/etc/rc.conf_mount_rw
fetch http://files.pfsense.org/kernel_new.gz
cp kernel_new.gz /boot/kernel/kernel.gz

EDIT: Modified code to reflect below change

eri--

With a little correction.
The last command is cp kernel_new.gz /boot/kernel/kernel.gz

@hugo,
if this results in a fix it will be included in the snapshots which will put it on amd64 snaps as well.

And then reboot.

And hopefully if it all goes as planned the next snapshot should have textdump support that works in it, and when it does panic it will automatically restart and leave the crash info in /var/crash in a .tar file that we can review. Works better than cell phone pics or swapping kernels… :-)

:D ;D :D OMG!!! I am posting this right now via OpenVPN on my neighbors wifi. It is working on my Soekris net5501-70 board so far and I haven't been booted. Will edit this post if it crashes doing more testing.

EDIT: Able to remote into everything fine, and trying file transfers

EDIT EDIT: Haven't had any problems since 5 with the network at home (Soekris). Still am testing the "work" one (em).

vito

just installed the latest snap with the kernel.

Looking good so far! :)
copied 1GB of data…no problem.

going to test some more.

clarknova

Ermal, please let us know when there will be a 64-bit kernel snap available for testing.

Jim, please let us know when there is a snap ready or in the pipe with textdump.

At the time I was logged on with 2 clients.  One (my netbook) was pushing pandora radio, and the other (my lappy) was working on configuration on the local network via remote desktop.  The desktop handshake for security (kerbros) is when it crashed.[/thread]

i have started facing this on my alix now using nanobsd, problem is when it crashes, webgui wont work nor does the serial console show anything so i have to simply power off and on again.

Slaygon

I can confirm the freezing on the latest build.
No indication on the console, nothing in logs, no crash dumps, nada. It's just stone dead.

Only thing you can do is to power-cycle the machine.

xbipin

so i guess im not the only one, im using the 26th jan snap and one way i could replicate is as follows:

alix booted and running and pppoe conencted, now i went to status -> interfaces -> wan interface and clicked disconnect and after some time it auto reconnects and now after say about less than 30mins and the system is dead.

eri--

xibpin and others please upgrade to the 27-JAN snapshot when its out.

Please do not mess this thread because it is because of another specific issue not related to the hangs which should be fixed on a 27-JAN snap.

The one that froze on me most recently was the 27-JAN snapshot ("2.0-BETA5 (amd64) built on Thu Jan 27 01:29:01 EST 2011").

LostInIgnorance

Should I just wait till the snap comes out? I never did get an answer concerning the test/crash last night loading the stuff ermal provided. Worked great, as you can see, for quite some time.

vito

ermal,
My openvpn connection is still up from last night.
Copied a good amount of data, no panics

So i know going forward,
Do i need to apply the new kernel with the newer snaps?

At what point will the new snaps contain the new working kernel?

Thanks again for all your help. (and of course jimp also) :)
