The code emitted at the start of precheck_file_write is:

precheck_file_write:
       pushl %ebp
       pushl %edi
       pushl %esi
       pushl %ebx
       movl 24(%esp),%ebp
       movl 32(%esp),%edx
       movl $-8192,%eax
[...]

I guessed inode to be ebp. the oops text copied from serial console (I 
lost the first line):

c01306fb
*pde = 00000000

I'm now a little less confident about that last crash because I was a 
bit hasty in getting another run started. I have since trampled over the 
supporting evidence (kernel, map, build output).
