I'm porting kernel 2.6.22.6 on custom embedded system (ARM1136).
During network subsystem initialization, kernel hangs in function
synchronize_rcu invoked by synchronize_net. In particular
wait_for_completion(&rcu.completion);
never returns and wakeme_after_rcu is never hit.
Anybody can give me any advice about how to investigate this issue?
void synchronize_rcu(void)
{
struct rcu_synchronize rcu;
init_completion(&rcu.completion);
/* Will wake me after RCU finished */
call_rcu(&rcu.head, wakeme_after_rcu);
/* Wait for it */
wait_for_completion(&rcu.completion);
}
Thanks in advance,
llandre
