May 14 23:00:12 mainland kernel: [<ffffffff81509b4e>] dump_stack+0x4d/0x6fI got this for a second time the last few day. Nothing i can think of that triggers it. 3.13 kernel seemed more stable. 
Also just in case it helps with anything i got oom-killer to close all the open apps which seems weird for a system with 12G of RAM (if i understand what oom-killer does).

Re: Kernel panic (kernel BUG at mm/slub.c:3392!)
I have also started getting the same kernel panic: kernel BUG at mm/slubc:3392
For me it has happened while on skype & google chat, apparently while attempting to unload the nvidia driver and, after/while closing a text file.
Actually about 2 updates ago, my system started to randomly (and i mean completely randomly) just freeze. No logs, nothing I can find to hint at the cause or the problem.
At leas these kernel panics leave dump information.

Re: Kernel panic (kernel BUG at mm/slub.c:3392!)
This sounds like an upstream bug. Quick googling shows something similar: http://forums.fedoraforum.org/archive/i … 97724.html
