Ok =) I hope in next week you found bug place and fix it!

PS. if you ask where i can read "kernel panic dump logic" literature and 
try find bugline in code.
I read dump and see that bug in function "rb_insert_color" + some shift 
(in asm?) that called from htb_dequeue? But in htb_dequeue not have 
calling rb_insert_color =( Or some nodes in trace was skipped?

Its for change up my education ;)
