@george1421 I may have found the issue with the menu. This is the output from http://192.168.1.88/fog/service/ipxe/boot.php note the rootfstype=ext42
:fog.reginput kernel bzImage32 loglevel=4 initrd=init_32.xz root=/dev/ram0 rw ramdisk_size=127000 keymap= web=192.168.1.88/fog/ consoleblank=0 debug rootfstype=ext42 loglevel=4 mode=manreg imgfetch init_32.xz -
@george1421 Yep, that’s exactly what @Zaarin noticed in his first post. Looks like a fat finger kind of thing that we all do every once in a while.

@Bob-Henderson Understand this is not an official comment, but if you are at a road block until the devs can resolve this issue, I have a way to hack around it.
You need to have access to the linux console and edit the following file.
/var/www/html/fog/lib/fog/bootmenu.class.phpSearch for
rootfstypeThere should be two in that file. The first one is what we need to edit.It should look something like this
$this->kernel = sprintf('kernel %s %s initrd=%s root=/dev/ram0 rw ramdisk_size=%s keymap=%s web=%s consoleblank=0%s rootfstype=ext4%s%s',Just insert a space between ext4%s%s making it look like this
$this->kernel = sprintf('kernel %s %s initrd=%s root=/dev/ram0 rw ramdisk_size=%s keymap=%s web=%s consoleblank=0%s rootfstype=ext4 %s%s',Save the file and you should now be able to boot into the FOS kernel. Of course we should wait for an official fix, but this will get you going.

@george1421 Confirmed, that works. Gotta love spaces!

This post is deleted! -
Pushed into current to have a space.

I ran into this same issue, just updated trunk to git 8022 (latest) and got the same kernel panic. I manually changed the file and was able to run though the host registration, but no host was registered at the server.
-
Version @ 8030 and I too receive the kernel panic when selecting from the pxe menu, deploy tasks set from the web work
-
Trunk version 8030 not solving the problem.
-
Version @ 8034 appears to be working fine now, thanks
-
8036 as well. Thank for your work. Topic can be closed.
Zaza.

Hello new to linux here, trying to get fog up and running in my Windows environment I have came across the Kernel Panic issue after installing a newer kernel to try to get my HP 600 G2’s to register. I tried to follow this solution however when i look at the BootMenu.class.php with vi and search for rootfstype nothing comes up so I’m at a big stand still here. Any help would be much appreciated.

@tkindle83 Please try updating to rc-1.

@Tom-Elliott Thanks Tom how do I go about this? I’m very very new to Linux.
