We got the results of a run of those changes through the autobuilder without the noise of other failures. The error reporting system shows: http://errors.yoctoproject.org/Errors/Search/?items=10&query=d687cdfd04f3d97923c93239ea902bb38e2ea336 and I believe we have the following issues: a) qemux86/qemux86-64 are throwing warnings about errors in logs b) perf has some weird make race c) the qemuarm build looks like qemu either segfaulted or was killed d) we're occasionally seeing 3.19 and 3.14 fetch failures: https://autobuilder.yoctoproject.org/main/builders/nightly-intel-gpl/builds/394/steps/BuildImages/logs/stdio https://autobuilder.yoctoproject.org/main/builders/nightly-oe-selftest/builds/87/steps/Running%20oe-selftest/logs/stdio To try and promote more sstate cache reuse whilst we sort the remaining issues, I merged the linux-libc-header part, we need to get the above fixed before the other pieces can merge.
