P.S.
There is a bug report for Ubuntu VMs going read-only has similar backtraces.
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1423672
There are some with "ext4_mb_generate_buddy" (NOT what John originally
reported) and some with "ext4_mb_release_inode_pa" (John's original bug
report). They seem to be mutually exclusive - if one appears the other does
not.
The ones with "ext4_mb_release_inode_pa" show up in kernel 3.13.? (Ubuntu's
3.13.0-54-generic).
Theo said of backtraces containing "ext4_mb_generate_buddy" - "I believe the
bug in question was fixed in a backport that first showed up in v3.16.2"
