Hi,

I have already reported this issue in [1].
One of the issue was solved.
Unfortunately, it looks like there is still a different problem here
(Ubuntu/precise AMD64).

I tried v4.10-rc1 and latest Linus tree up to...

commit 98473f9f3f9bd404873cd1178c8be7d6d619f0d1
"mm/filemap: fix parameters to test_bit()"

Here we go...

On suspend/resume I see the same call trace.
[2] points to the "BUG" line.

Please, see attachments.

Any help appreciated.
