I found Linux hangs when printk is inserted to the function schedule(). Sure, it doesn't make much sense to add such a line to schedule(). But Linux shouldn't hang anyway, right? It's assumed that printk can be inserted safely to anywhere. So, is it a bug of Linux?
The linux I am running is 2.4.18-14, the same version used by Redhat 8.0. The scheduler is Ingo's O(1) scheduler.
Here is a fragment of the code **************************************************************** switch (prev->state) { ------ default: printk("deactivating task pid=%d comm=%s\n",prev->pid,prev->comm); deactivate_task(prev, rq); } ******************************************************************
