Subject: [BUG] NULL deref in swapin_readahead

Hi suspend gurus,

I got the attached NULL deref while closing and immediately reopening my 
laptop lid. The laptop is configured to suspend to RAM.

Google yields nothing similar for "unable to handle kernel NULL pointer 
dereference" "swapin_readahead" "radix_tree_lookup", so I guess this is 
an as-yet unknown problem. If not, please excuse the noise.

Kernel (vanilla 3.1.0) config attached. The laptop is a MacBook4,1.

The machine goes on to print a series of soft lockup reports, but I 
assumed they are PTSD and omited them.

With kind regards,

Wouter Koolen
