e2a21467e1 Updates to show "4.7" and other changes to major headers should be temporarily suspended
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
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.
