6285 - Kernel panic not syncing when trying to image

[Hanz]

@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

[MRCUR]

@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.

[Wayne Workman]

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.

[Tom Elliott]

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

[MRCUR]

@Tom-Elliott Same issue.

[Tom Elliott]

Are you sure both cloud versions are the same?

Can you test with some basic moving tricks?

mv /var/www/fog /home/fog/web
rm /var/www/html/fog -rf
rm /var/www/fog -rf

Then rerun the installer?

The only reason I move it first is so if you have any special iso’s we can recover them later on.
