Hi, There are at least a couple of intermittent issues where we would welcome some help and we now probably have enough information to allow debugging/progress.
Firstly, we suspect there is a reproducibility issue arm to x86. This is summarised with this reproducibility diff: https://valkyrie.yocto.io/pub/repro-fail/oe-reproducible-20260726-9wb1l3t4/packages/diff-html/ (from https://valkyrie.yocto.io/pub/repro-fail/oe-reproducible-20260726-9wb1l3t4/packages/diff-html/) I suspect what happened here is that the qemux86-64 files were built first on an arm host rather than an x86 host. In general the x86 hosts probably beat the arm hosts to it, hence why this is rare. To test/reproduce this, I'd suggest picking a target machine (say qemux86-64) and then building diffutils on both an x86-64 based host and on an aarch64 host. Comparing the ptest package will probably result in a diff similar to the above, e.g.: build_triplet·=·aarch64-unknown-linux-gnu vs. build_triplet·=·x86_64-pc-linux-gnu in usr/lib/diffutils/ptest/tests/Makefile amongst other things. I suspect picking MACHINE=qemuarm64 would have the same result. If that reproduces the issue, it would then be a case of iterating through the differnces and finding a way to reconcile the output so it is the same, independent of build host architecture. The second issue where we could potentially take help is with https://bugzilla.yoctoproject.org/show_bug.cgi?id=13908 This is the infamous matchbox segfault, now strong suspected to be the xserver restarting during boot. There are several things which could help here: * finding out whether it always restarts the xserver? * is there a way to crash the xserver like that (race with psplash for the console?) * working out if we can reproduce the matchbox crash using some delays placed in some of the code to widen the race window? Given what we suspect is happening, we can likely improve the code to exit cleanly when the suspected memory allocation failure occurs rather than crashing too. Cheers, Richard
