I am not sure why the kernel paniced after being up for a long time, but 
I was wrong about why. I wasn't feeling well today and was rushed to try 
to reboot the machine and didn't carefully check which kernel I had actually 
tried to boot and confused the version of the oldest kernel with that of 
another machine.
