Subjectspin_unlock hang, and IRC question
Hello!

First, anyone know why I get this when trying to log onto #kernel IRC
channel?

greear sets mode +i greear
--- You have been killed by mid.eu.linuxnet.org (Username))
--- Closing Link: dhcp101-dsl-usw4.w-link.net greear (Killed by mid.eu.linuxnet.org (Bad Username))
--- Disconnected (Remote host closed socket).


Now, for the real question: I'm making pktgen threaded. It works great on
a single processor (compiled for single processor). But, it hangs quickly
when used on an SMP (Athlon 2Ghz-equiv) machine.

I put in print statements (I would love to hear other ideas for how to debug)
and it seems that the system hangs trying to unlock a spin lock. Specifically,
I see the first printout, but not the second:


inline static void pg_unlock(struct pktgen_thread_info* pg_thread, char* msg) {
if (debug > 1) {
printk("before pg_unlock thread, thread: %x msg: %s\n",
pg_thread, msg);
}
spin_unlock(&(pg_thread->pg_threadlock));
if (debug > 1) {
printk("after pg_unlock thread, thread: %x msg: %s\n",
pg_thread, msg);
}
}


Any ideas for how to go about debugging this will be greatly appreciated!

Thanks,
Ben
