Huh? The driver core operates with no sleeps and runs in the process that it was called in, so I don't think it would be sleeping 2 seconds. But enable debugging in the driver core (it's a config option) and see what the timestamps tell you (enable the printk timestamp option, it's very useful for stuff like this.) thanks, greg k-h ------------------------------------------------------------------------- Using Tomcat but need to do more?
