Josef and I both missed this the first time you pasted it, but the
unlocked page is almost certainly related to this csum error. While
we're looking at things can you please scrub?
Josef and I just read through all of this, and I'm not finding a way to
connect the crc error to the BUG_ON. Do all kernels crash like this, or
was it just 4.1-rc?
The csum error was for one of the files. Scrub did not fix it. When I run Scrub
it shows 0 error. So I deleted the file. I do no see the crash now.
Crash did not happen on 3.18 kernel. I first faced this problem in 3.19.
