Additional... I enabled SLAB_DEBUG_SUPPORT and got no additional
printk's regarding slab debug errors.

A little more information... with code inlined, it made it a bit
difficult to pinpoint.

The failing instruction is just inside ->   if (slabp->s_magic !=
SLAB_MAGIC_ALLOC)
in __kmem_cache_free().  

Code;  c0122770 <kfree+7c/1ac>
00000000 <_EIP>:
Code;  c0122770 <kfree+7c/1ac>   <=====
   0:   8b 69 08                  mov    0x8(%ecx),%ebp   <=====
Code;  c0122773 <kfree+7f/1ac>
   3:   81 fd 2b 2f c3 a5         cmp    $0xa5c32f2b,%ebp
Code;  c0122779 <kfree+85/1ac>
   9:   0f 85 d1 00 00 00         jne    e0 <_EIP+0xe0> c0122850
<kfree+15c/1ac>

The question is how is my code or the hardware corrupting the slab?
I'll see what I can figure out in Bovet's book.

Thanks in advance.
