Hey Eric,
This is a pretty late response to the thread, but in case you're
curious, since Ubuntu forgot to backport this (I already emailed them
about it), I actually experienced a set of boxes that hit this bug in
the wild and were crashing every 2 weeks or so, when under highload.
It's pretty amazing that syzkaller unearthed this, resulting in a nice
test case, making it possible to debug and fix the error. Otherwise
it'd be a real heisenbug.
So, thanks.
Jason
