--- Comment #2 from Jan Kara ---
Looking into the traces, this doesn't seem to be ext4 problem at the first
sight. We are waiting in filemap_fdatawait_range() for IO on the page to
finish. It seems that never happens which would be a bug somewhere in the block
layer, device mapper, etc. Seeing that you mention bcache, would it be possible
to try whether the hangs happen without it?
