[DragonFlyBSD - Bug #2927] e2a21467e1 Updates to show "4.7" and other changes to major headers should be temporarily suspended

[bugtracker-admin at leaf.dragonflybsd.org]

Issue #2927 has been updated by davshao.


Multiple machines including the Intel i3-3225 CPU and the AMD Athlon II X4 610e CPU machines have successfully
completed a full
make -j7 buildworld buildkernel

Thanks for all the hard work to debug this!

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.
