6285 - Kernel panic not syncing when trying to image

[MRCUR]

Upgraded from SVN in the 3000’s (build from July sometime) to 6285. When trying to image a client (or register them, anything that requires access to the menu), I get an error of Kernel panic - not syncing.

Reran the installer again to get the inits downloaded (which says OK during install) and problem still occurs.

What hardware are you trying to image? Do you know the boot file you’re using?

@Wayne-Workman This is happening to me as well…SVN6267 was last known working version…https://forums.fogproject.org/topic/5642/end-kernel-panic-not-syncing … this link shows the exact error I’m getting…however; this is happening while trying to multicast or singularly try to image from storage node. Imaging from server itself works fine.

Currently running SVN 6287

@Wayne-Workman I’m testing with an HP ProBook 640 G1, which works fine on a separate SVN install (also worked fine on the previous rev I was running).

Boot file is undionly.kpxe which it was before and is the same on the test server where this works fine.

Can one of you try kernel 4.4.0 ?

[MRCUR]

After talking to @Wayne-Workman, this seems like it might be an issue with the symlink being used to make /var/www/html work on Ubuntu where the root is really /var/www.

@tom-elliott I see in .fogsettings there’s a line for “docroot”. If I update that to be /var/www/ instead of /var/www/html/, will that work?

[Tom Elliott]

@MRCUR If you want to give it a shot, maybe.

[MRCUR]

@Tom-Elliott Changed the docroot to /var/www/ and didn’t have any success. Tried the 4.4 kernel as @wayne-workman suggested without success either. Same issue.

[Tom Elliott]

@MRCUR Can you post a pic of the panic?

[MRCUR]

[Wayne Workman]

@MRCUR How many devices have you tried on? Just this laptop?

[Hanz]

@Wayne-Workman This exact error is what I’m getting as well…hardware worked previously so it’s in the code.

[Tom Elliott]

@MRCUR Is bzImage32_4 a valid file? Meaning is it a full on filename in /var/www/{html,}/fog/service/ipxe/ and what’s the size?

[MRCUR]

@Tom-Elliott It is, yes. Downloaded through the kernel update GUI as suggested by @Wayne-Workman. This also happens with the default 4.4.1 kernel.

@Wayne-Workman This is happening on all of our hardware that I know of. I’ve specifically been using HP ProBook 640’s and 440’s today while testing. I have a 440 sitting at my desk now which is displaying the issue.

[MRCUR]

@Tom-Elliott I should mention that this hardware works fine with my test server (currently rev 6285 on 14.04 LTS, same as production server) using the default 4.4.1 kernel.

[Tom Elliott]

@MRCUR So it works on one, but not the other?

[Tom Elliott]

@MRCUR Also, can you get output from the browser?

http://IP.Of.Fog.37/fog/service/ipxe/boot.php?mac=c4:34:6b:06:5b:20

Of course I don’t know the ip so please change the relevant info as needed.

[MRCUR]

@Tom-Elliott Right. The test server was SVN from the start (not sure what rev I started with), the production server was originally 1.1 or 1.2 and upgraded to svn over the summer and then this week to 62XX series.

@MRCUR can you, for now, disable hidden menu, and see if this fixes the problem?
