It has been a long time since I last updated the kernels on my linux machines. I had managed to keep the software up to date but the kernel upgrades are always a little more involved. Today is the day that they were all updated, all the software updated and rebuilt. Optimising the kernels is a little more time consuming and it may take another attempt on my main machines to get rid of any extra drivers and features that are not required.
I wont be suprised to see another kernel released any moment to undo my hard work, its just the way it goes.
