Subject: rcu_sched self-detected stall on CPU

Hello,

I've been testing out KASAN and experimenting with some other new
config settings related to security and kernel hardening, I ran into a
problem though and I've attached a snippet of my kernel log of the
stack trace as well as my kernel config. Also intermittently (every
few seconds just about) my system freezes for a short moment and
resumes, no errors pop up though in dmesg. My mouse just stops working
and the system is basically very choppy and sluggish, most likely
related to KASAN from the looks of it. I'm running a 4.2 GHz quad core
APU, if you need any more info let me know! (Kernel image is nearly
9MB with XZ compression!)

Thanks!
