Oops, yeah. I skipped a line, but page fault nonetheless ;-)

The rest of the theory should still hold. The pointer being
dereferenced is held in %eax, which is c6798550. This fits with the
reported address:

[   76.583958] BUG: unable to handle kernel paging request at c6798558
...
[   76.584019] EAX: c6798550 EBX: 00000000 ECX: c678b000 EDX: c678b038

Thanks for the correction.
