Issue #2927 has been updated by davshao.
Even after commit 1a5c7e0f9aa6bc9a632a92b6b832cfe676746f7f Date: Sat Jul 23 19:19:46 2016 -0700 kernel - Refactor Xinvltlb a little, turn off the idle-thread invltlb opt make -j7 buildworld locks up on both an Intel i3-3225 CPU (Ivy Bridge, 2 core with hyperthreading) Asrock Z77M motherboard machine and an AMD Athlon II X4 610e CPU (quad-core) Asus M5A87 machine. ---------------------------------------- Bug #2927: e2a21467e1 Updates to show "4.7" and other changes to major headers should be temporarily suspended http://bugs.dragonflybsd.org/issues/2927#change-12947 * Author: davshao * Status: In Progress * Priority: High * Assignee: dillon * Category: * Target version: ---------------------------------------- commit 5d920ec6b97613f06aba4a09bfb91413b1fd93c3 Fix excessive ipiq recursion (2) does not correct the problem I have observed on at least two machines that make -j7 buildworld locks up the machine. (When using make buildworld I move /usr/obj/usr to start the build from scratch.) On one machine there seems to be a reproducible lock up at sh /usr/src/tools/install.sh -o root -g wheel -m 555 lto1 /usr/obj/usr/src/ctools_x86_64_x86_64/usr/libexec/gcc50 Changes to major headers should be temporarily suspended until this problem is resolved, because I have observed that even make quickworld can fail to complete without lockup. Someone using UFS as their filesystem may experience quite substantial filesystem corruption after a lockup. By limiting changes to major headers, this gives the greatest chance of a successful make quickworld when this problem is finally resolved. -- You have received this notification because you have either subscribed to it, or are involved in it.
