Thank you very much for reporting.  That BUG is a 3.15-rc regression.
3.14's try_get_mem_cgroup_from_mm() had protection against NULL mm,
as when exiting.  That was correctly removed as unnecessary by one
3.15 commit, but a new caller added in a later commit: which made
it necessary again, as you have now found.

Easily fixable, but opinions will differ on the right way to write it
(and I'm rather out of touch with the current flux in css_tryget and
root_mem_cgroup), so Cc'ing Hannes and Michal for the definitive fix.

Or does that backtrace say that it's a kernel thread that was exiting
(and being accounted)?  A kernel thread would not have had an mm in the
first place.

I know very little about accounting (acct_process etc).  You said above
"Programs could be started but they will not finish": I'll assume that
hitting such a BUG inside acct_process() led to that.

Then a good interval of 85 seconds.
