Kernel Panic

FisherKing

Text dumps will be a nice feature. Thanks for working on that Jimp.

cmb

On the setup we have where secondary panics used to be replicable it's fixed now.

jnorell: can you email me a backup of your config? cmb at pfsense dot org

Uploaded a new kernel http://files.pfsense.org/kernel_new.gz
Beaware that you need to be updated to the latest snapshot before using this kernel otherwise you will get hangs.

LostInIgnorance

Is this just for the intel em chip fix? or will it also work on my Soekris vr chip?

@ermal:

Uploaded a new kernel http://files.pfsense.org/kernel_new.gz

Is that for full installs? amd64?

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.

clarknova

And then reboot.

jimp

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… :-)

LostInIgnorance

: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.
