Somewhere between 5 and 5.1. I had to stick with the original kernel until some later kernel fixed the problem. It was around the time the system recognized my video, I believe. Kernel problems happen. At work, with the upstream vender, one of the 5.1 era kernels didn't handle the Pentium III on one of our systems very well, and would panic in some Athlon power management driver. Later, it too was fixed. I just upgraded my home system today, and it came up fine.
