In case it helps those searching for the race condition in uvm, on
ppc64 I'm still seeing the problem I reported in May. This currently
prevents running the Go build server, since I do not know how to
control parallelism in their LUCI infrastructure. I regret that I
do not have the skill to narrow this bug report, but am happy to
test patches.
With a fresh sysupgrade -s, compiling a kernel from source works
fine and so does "cd /usr/src; make obj && time make build".
Early in the year, I used to be able to build with -j24 but no longer.
cd /usr/src
make obj && time make -j8 build
