I don't think so: I haven't had a single failure with new kernels since the early days of 3.x. That's including server, desktop, laptop and media center. > I usually wait until the current release > gets to the 3rd or 4th revision before updating to make sure all the > bugs are out. If I understand correctly, that was the smart thing to do in the awful old days, when we had the even middle numbers for stable releases and the odd ones for unstable. However, in the new (and IMO, better) rolling releases, the bugs are ironed out in the RC series. Specially with relatively new hardware, going with the latest relese is usually always a good call, IMO. > Had a few times where my laptop was not a fan of new > kernels - 3.16.1 wouldn't boot, for example. That sounds like a bug. Also, sometimes some kernel options change name or location, and your old configuration file should be updated. I'm not saying that's what happened, but it could be. >> And with systemd, rebooting to a new kernel takes just a few seconds ;) > > Must be nice; my laptop is so old that it boots slowly regardless of my > choice of init system. You should try getting it an SSD. It brings back old laptops from the grave: most desktop software has been I/O bound for some time, and with a fast SSD, even an old laptop can become usuable again.
