Testing is a good thing, but most system updates within a
distribution version are in the form of very specific
bugfixes backported in a way that tries not to break anything
that already works.  If this is the first reboot after an
update that installed a new kernel you may have hit a rare
exception.  However, the kernel does not replace the old
one.  You have a few seconds during a reboot to select a
non-default kernel.  I'd try going to the previous one
first to see if that fixes your problem, but also look
around at the network to see if anything else has changed
and check the dmesg output and system logs if the problem
remains.
