Hi Daniel,

there is a fix bug that happens when resizing the file system in a way
that a new size is still in the same group:

a0ade1deb86d2325aecc36272bb4505a6eec9235
	ext4: fix resize when resizing within single group

I am not sure if that really solves your problem, since the actual bug
in you backtrace happens somewhere else, but you can give it a try. It
was merged into the main line just recently.

Thanks!
-Lukas
