Dear Jason A. Donenfeld,

in my case it is easily reproduceable. I have an SD-card in our embedded
device (AVR32 AP7000). Some random data is continuously written to an
FAT filesystem on that device. When you pull the card out of the slot
you trigger that NULL pointer dereference.
I will try to reproduce that error on my workstation but this will need
some time. Maybe I can not hit that race on my quad core workstation but
I will give it a try.
