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?

It looks to me like some locking is missing or interrupted. > If you are working weekends and find something new, don't wait: maybe > somebody else here could be interested too. > > Cheers, > Jarek P. > >
