There's not many tracepoints, but from my previous emails I added some
trace_printk()s and converted some of your debug prints into
trace_printk():


+#undef dprintk
+#undef dprintk_rcu
+#define dprintk(args...)       trace_printk(args)
+#define dprintk_rcu(args...)   trace_printk(args)


See my previous email that describes all this (I removed the debugging
from my kernel, and I need to spend time with the family so I can't get
to this again till Tuesday)
