Just a heads-up in case you hit this, or want to avoid it.
The symptom is BUG: scheduling while atomic
The discussion at
confirms that it's the low-latency path that is buggy.
My setup works fine under low load, but hits the BUG when I do something like
compile the ntp package.
3.11 works fine. (for me) There was major work in the serial area for 3.12
I'll send an update when/if it gets fixed.
These are my opinions. I hate spam.
