Hmm, we are waiting for buffer lock so likely someone is writing that inode
out. It would be good to have stack traces of all hanging processes at that
moment to tell what they are doing.

So can you please do one more run and when things like suspiciously long fstat
happen, run as fast as possible "echo w >/proc/sysrq-trigger" and attach here
the output? Thanks
