Thanks. 

Current situtation:

sander@superstreamer:~$ uptime && dmesg | grep -i -e "Linux version" -e slub
 22:22:32 up  2:59,  1 user,  load average: 1,74, 0,90, 0,70
[    0.000000] Linux version 3.18.0-13-generic (buildd@komainu) (gcc version 4.9.2 (Ubuntu 4.9.2-10ubuntu5) ) #14-Ubuntu SMP Fri Feb 6 09:55:14 UTC 2015 (Ubuntu 3.18.0-13.14-generic 3.18.5)

sander@superstreamer:~$ 


So:
1) still no slub.c messages; that's good.
2) The "Linux version" does show "Ubuntu 3.18.0-13.14-generic". Is that your kernel version? I'll do the download & install procedure once again anyway:

lynx --dump http://people.canonical.com/~henrix/lp1418286/v1/ | grep http | egrep -e ".*deb" | awk '{ print "wget " $2 }'  | /bin/sh
