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? -- You are receiving this mail because: You are watching the assignee of the bug.
