This first git pull fixes it for me, as far as I can tell. I'm not
sure that the problem is 100% reproducible, but I booted into each
kernel twice, and the current git tree is broken, while with your
psr_setup_time_2 branch pulled it works.  So it does seem to be the
fix.

I didn't even test that one.

Should I just pull that psr_setup_time2 branch for real? I'd like to
get a real pull request with explanations etc, but other than that it
looks good to go.
