I've been looking through the various commits:
What is odd about the 3dd8 commit (i.e. the fix I mentioned in the first
mail) is there is code that says:
if (test_bit(STATUS_INT_ENABLED, &priv->status))
I presume test_bit returns "true" if the bit is set? If so, then the
call, is a little strange as iwl_enable_interrupts sets the bit again.
So it's only enabled if it's already set? Perhaps test_bit returns 0
when it's already set?
172 static inline void iwl_enable_interrupts(struct iwl_priv *priv)
174 IWL_DEBUG_ISR(priv, "Enabling interrupts\n");
175 set_bit(STATUS_INT_ENABLED, &priv->status);
176 iwl_write32(priv, CSR_INT_MASK, priv->inta_mask);
But I'm no kernel hacker, so all this could be rubbish.
