Just got something - not on the console but a livelock with
4.5.0-rc5-dirty. However, this seems to be mm-related?
This one has git checkout of v4.3 + git checkout master running, ps
hangs when reaching this process. Simple pstree works, pstree -plah
hangs, pstree -cp whows 3 gits running, catting /proc/PID/cmdline of one
of them is hanging again. wchan is vm_munmap, status shows state D as
expected.
