Thanks very much for your work. I hate to see work repeated, but I've already
done most of this backporting myself. The only reason I haven't released it
is it still creates problems greater than what it fixes. Only when they're
all fixed will I release it.
1000Hz is of dubious advantage to desktops as far as I can see, but I have no
objection to it being definable (as well as the scheduler tunables). I was
thinking perhaps 200Hz would be good enough for a desktop without the
unnecessary overhead of 1000Hz - and it is a very real disadvantage on a
desktop.
Anyway I'll see if the latest scheduler tweaks have fixed the hangs in the new
scheduler and when they do I'll post an official update to -ck*.
Cheers,
Con
