The message itself should be no problem, except in the volumes you're getting it... a plain "resume" message comes when ohci_hub_resume() fires, and that should happen only after INTR_RD. But that IRQ shouldn't be happening very quickly, and it seemed your system was getting gobs of them. > Is there anything else that I can help you? Find out whether that hardware is for some reason broken, so that it issues INTR_RD when it shouldn't. That includes verifying that the interrupt counts in /proc/interrupts are absurd for an idle USB host. Also, verify that the messages stop if you get rid of CONFIG_PM. - Dave ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
