Hello!
Houston, we have a problem! When building latest stabweek world in poudriere on my aarch64 machine, I've got an error in libthr when pkg command is called: ===> Creating FreeBSD-kernel-generic-nodebug-16.snap20261026210619 Fatal error 'mutex 0x41814480 own 0x8c935 is on list 0x0 0x409e0008' at line 154 in file /opt/poudriere/jails/16aarch64/usr/src/lib/libthr/thread/thr_mutex.c (errno = 0) Abort trap (core dumped) Host system was a 16.0-CURRENT #0 main-461da47e45e7: Sun Oct 18 02:22:28 MSK 2026 Same error on host FreeBSD 16.0-CURRENT #0 main-5250c9890848: Tue Oct 27 00:49:17 MSK 2026 But when I revert host to 16.0-CURRENT #0 main-17af098383ba: Fri Sep 18 23:23:19 MSK 2026 all builds runs without any errors Looks like some of latest commits between Sept 18 and Oct18 in libthr causes this failure 4472a048cf95c9c1593a8b04655a59096b44b0c9 192781bf5d047cceff3a1947bfc754c8b5eb0835 1d21e67e720a08992e81d626cff9d76524a81f22 627e7d5b72cf967eae3cd9e9e0707ce0ff63a4da 99edcc3bd52614c6cf972ea8424a7807ed3fe1e3 de2c0f157a9cce0b763da9ae97ada870fa4d1824 305c3044e0249ea24a9b4571dfa6ae319a5bcdec 5fb07bbcd5d5d9a865d9e7765fb93e9ba5edef1c a0e152973613e0d0d55257f4e1f614509b7ec4c9 894f70a2bd8c7f67f131b76b9ce122a752818af3 On 26.10.2026 11:00, Gleb Smirnoff wrote:
Hi FreeBSD/main users & developers: This is an automated email to inform you that the October 2026 stabilization week started with FreeBSD/main at main-n290336-175595ba6c52, which was tagged as main-stabweek-2026-Oct. Those who want to participate in the stabilization week are encouraged to update to the above revision/tag and test their systems. The tag main-stabweek-2026-Oct has been published at Gleb Smirnoff's github repo. To connect this repo as an additional remote you need to run: git remote add glebius https://github.com/glebius/FreeBSD Once remote is configured, to checkout the tag run: git fetch glebius --tags git checkout main-stabweek-2026-Oct If you want to use only the official FreeBSD repo, then update to the revision: git pull git checkout 175595ba6c52 Developers are encouraged to avoid pushing new features to FreeBSD/main during the stabilization week, but focus on bugfixes instead. The stabilization week runs up to Friday 18:00 UTC, but if there is consensus that any regressions discovered by participants have been fixed, it will end early. Once that happens, the advisory freeze of FreeBSD/main branch is thawed. -- Gleb Smirnoff
