2021-03-18 Thread Rainer Fiebig
Hi! I tried kernel 5.10.x and encountered a strange problem: building the same kernel (5.10.22/23) took roughly twice as long as under 4.19.179. This is reproducible under kernels 5.9, 5.8 and 5.6. The latter is where it apparently starts, kernel 5.5 is not affected. Here's an example: 5.6 buil
