Jekyll and pygments using nasm - jekyll

Question

I'm trying to get my nasm syntax highlighted in Jekyll using pygments. It works flawlessly for C and Python, but nasm doesn't seem to work.
```nasm
section .text
global _start
_start:
xor ecx, ecx
mov al,15 ; changed push pop to mov
push ecx
push byte 0x77
mov cx,0x4d42 ; random addition before pushing
add cx,0x2222
push cx
push 0x6168732f
push 0x6374652f
mov ebx, esp
push word 0x1b6
pop ecx
int 0x80</p>
mov al,1 ; changed push pop to mov
int 0x80
```
Instead of embedding everything in span tags it just produces this:
<div class="highlight"><pre><code class="language-nasm" data-lang="nasm"> section .text
global _start
_start:
xor ecx, ecx
mov al,15 ; changed push pop to mov
push ecx
push byte 0x77
mov cx,0x4d42 ; random addition before pushing
add cx,0x2222
push cx
push 0x6168732f
push 0x6374652f
mov ebx, esp
push word 0x1b6
pop ecx
int 0x80</p>
mov al,1 ; changed push pop to mov
int 0x80
</code></pre></div>
This is my _config.yml:

description: "Blog"
gems: [jekyll-paginate]
url: "http://cloud101.eu"
paginate: 10
markdown: redcarpet
