If you did not notice what packages were being update, you can use the
software centre to show you a list of all the packages added and upgraded.

A guess would be a kernel upgrade, or kernel modules.  If you select the
older kernel when booting the computer you can quickly test if this is the
cause.  You should still have the previous kernel installed unless you
specifically asked Ubuntu to remove it.

Thank you.
