This might simply be a symptom of the earlier "Unable to handle
kernel paging request at virtual address 708ebbfa". However, the
usual cause of the later "rcu_read_lock() used illegally while idle!"
is just that. In this case, might the interrupt have occurred
without irq_enter() being invoked?
(But there are probably two interleaved stack traces, and I am not
certain that I am getting them untangled properly.)
