Tomoyo causing kernel panic

I've recently installed Arch, and I set up Skype with Tomoyo as per the wiki, and it worked well.

Today when I booted, I got a Kernel Panic - not syncing: STOP! error.  This error went away when I removed the 'security=tomoyo TOMOYO_trigger=/sbin/init' from my APPEND line (I'm using Syslinux).

I have installed some updates and new packages since my Tomoyo setup, but I tried uninstalling those packages and returning the machine to the last known good state, with the same result - TOMOYO causes a kernel panic.

I've also tried reinstalling tomoyo-tools.

The system boots and runs fine without the Tomoyo option in all cases.

Any suggestions as to what to look for next? 

Thanks!

Re: Tomoyo causing kernel panic

So just to be clear, are you able to start tomoyo after you have fully booted?  Maybe you just need to delay when it starts up, or use something like .xinitrc to start it.

Re: Tomoyo causing kernel panic

Is the Wiki updated for sbin move?  Look at line 6010 https://projects.archlinux.org/svntogit … ages/linux
That is no longer sbin but usr/bin.

Re: Tomoyo causing kernel panic

It should work although updating it to the "right" path might not be a bad idea.

> file /sbin/init
/sbin/init: symbolic link to `../lib/systemd/systemd'

# file /usr/bin/tomoyo-init
/usr/bin/tomoyo-init: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.32, BuildID[sha1]=2b3f01f527264d09baf36a999c917c27acd397d7, stripped

I used to have 'security=tomoyo TOMOYO_trigger=/usr/lib/systemd/systemd' until recently. I stopped using tomoyo because it is a bit too much work to keep the rules up-to-date. Stuff tends to break when you most need to use it, not fun.
