Kernel Panic
-
Thanks for you prompt support.
I've upgraded to 21 Jan 23:51 but the secondary still crashes, do you need a backtrace? Or is this snapshot not new enough?
thanks -
I am still getting the panic on my home Soekris net5501-70 board when using openVPN. I am unable to load the developer kernel on here since the board is an embedded system without a display. The board refuses to boot once loaded with the developer. Is there another way to grab the panic? I am using a HD in place of a cf card since I am running squid and HAVP.

Hi, I've upgraded to version: Sun Jan 23 01:37:41 EST 2011, changed to devel kernel and the system doesn't boot any more, see the attached pictures.
Thanks

Tested with snap
2.0-BETA5 (i386)
built on Fri Jan 21 06:52:27 EST 2011Still not working.
Thanks!

Looks like the e1000 (em and igb) driver from 8.2-STABLE saw quite a few updates/fixes and we may have to pull that in. I'll post in here when something gets committed (or you can just follow the commit log on the tools repo)
-
Commit just happened with the changed drivers. Next snap should have them, assuming they build OK.
-
So that should fix the gig card issue, but what can I do to get the full backtrace on my embedded Soekris board?
-
We don't have an embedded debug kernel, not sure how hard it might be to make one. If it doesn't work properly with the full install's debug kernel, it may be a pain to do.
-
Jimp,
I will let you know after the next full update snap.
from another post, are the snaps building fine now? (or the server, what ever the problem was)Thanks again!!
-
I will let you know after the next full update snap.
from another post, are the snaps building fine now? (or the server, what ever the problem was)The build won't be restarted for a couple more hours (waiting on patches for other issues to go in, too) so it probably won't be uploaded until tomorrow AM.
The snapshots were building fine all weekend, but at one point the snapshot web server (where they are copied after being built) ran out of space. It's OK now.
-
Yeah I tried the full install from the cd on the hd, but the board wouldn't boot. Had to stick with the embedded build.
-
Soekris won't boot from USB. You have to put your boot media in another machine to do the install. Once you have the drive back in the soekris you will probably have to manually enter your rootfs device at the prompt, then update /etc/fstab.
-
that is exactly what I did, using vm and an external usb-sata adapter. Just wish I could get the developer to boot on the board. I should have specified I used a usb dvd since I don't have one on my netbook.
-
I have installed 1.2.3 and 2.0 on a net5501-70 a few times, never had a problem other than changing the root device. Post specifics if you want help troubleshooting it.
Have you tried installing the full developer kernel on the embedded install?
-
last time I tried to do what PJ2 outlined at the begining of this thread, it locked my system up and wouldn't boot. Help is always greatly appreciated if I can get it installed and get the panic.
EDIT: Would actually prefer having the developer kernel on this embedded device. I am using the 5501-70; sata wd 80g; running full embedded; vr0-wan, vr1-lan, vr2-wrls (friendly wifi for visitors), vr3-dmz; packages squid, lightsquid, nut, havp, nmap, snort; anything else?
-
I just added support to the builder to make an embedded kernel with debug options. I've got a test build going on my box, if one cranks out I'll upload it somewhere this evening or tomorrow. Failing that, the main snapshots should include it from here on. Not the next snapshot, but the one after it, should have them.
-
OMG, THANKS JIMP!!! I am excited to know if it works!
-
For those wanting to debug on ALIX/other embedded devices…
/etc/rc.conf_mount_rw fetch http://pingle.org/files/kernel_wrap_Dev.gz tar xzpf kernel_wrap_Dev.gz -C /boot/And then reboot. It works on my ALIX.
The next snapshot after the one building now should have them in there as well, but not the one building now.
-
JimP, the above mentioned code worked great on my Soekris net-5501-70 board. Thanks for that, I hope to drive down the road and use my neighbors wifi to see if I can crash it now.

Grabbed the panic from the above mentioned Soekris board.
