I think this was just me being an idiot. I forgot that I'd been
running with KASAN, so that explains why my speeds were so much slower
than usual and probably also explains how it could get in a bad state
(I guess it also explains why sugov was eating up 30% of my CPU time
since that went away too!). No mystery here aside from why it took me
this long to realize it.
I'm now getting ~213 MB/s without forcing it to lazy and ~261 MB/s
with forcing it to lazy through sysfs (and without any other cpufreq
hacks).
-Doug
