>>> EIP: 11b1b8 <insert_vm_struct+48/2e8>

eax = "FeL+" in ascii. It could be plain text, but it is certainly not
a kernel address. According to the disassembly of insert_vm_struct, it
is supposed to be the address of a vm_area_struct, namely the
mm->mmap_avl root point. The mm's entire mmap tree is corrupt --- bad
news.

Given that I'm not seeing this from anybody else, hardware memory
corruption is still the biggest likelihood. On the other hand, are you
running any unusual loads (heavily threaded programs etc.) which might
be contributing?
