This included +the boot itself, especially the first one, since first boots tend to do +a significant amount of writing due to certain post-install scripts. + +The problem (and solution) was discovered by using the Yocto tracing +tools, in this case 'perf stat', 'perf script', 'perf record' and 'perf +report'. + +See all the unvarnished details of how this bug was diagnosed and solved +here: Yocto Bug #3049 |
