Well, it finally happened, the wireless driver got wedged on my laptop meaning I was done with wireless and suspend until a reboot. Final uptime was:

07:22:01 up 52 days, 18:27,  1 user,  load average: 4.67, 13.07, 11.02

before I had to reboot. It did mean I could take all the kernel updates I need to, as well as update wireless drivers.
