Subject: 3.0 does not survive make -j [sic] on a kernel tree
make clean ; make -j hangs quickly, 100% reproducibly. The system
answers pings but is otherwise completely unresponsive. The
softlockup detector output and eventual oom is below. The system does
not appear to recover.
The correct answer is "don't do that". But this seems like poor behavior.
