Subject: [Bug 102731] I have a cough.

https://bugzilla.kernel.org/show_bug.cgi?id=102731

--- Comment #25 from cwseys@...sics.wisc.edu ---
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"
