The system is working now. I have been taking backups on the external drive connected to the 4-port hub it since yesterday. The backup (a large one) ran for several hours until late at night without a hitch. Since this morning the system has booted fine and has not shown any sign of crashing.
Thanks to Christophe Penalver for his detailed instructions on how to upgrade the kernel, I upgraded to a mainline kernel. The kernel is linux-kernel-4.0.0-040000-generic.
I am marking the status of this bug as "CONFIRMED".
I have also added the tags as suggested by Christophe.
