Hi, I am doing some testing on an MCA tokenring adapter on server-9595. Inserting the drivers ( as module) it is perfect. But when I do an ifconfig tr0 up then I get an kernel Oops at the point interruptible_sleep_on_timeout() function inside the driver open function.. I could find no problem as far as driver initialization and openig is concerned . I an using kernel-2.4.0 with redhat -7 installation. Is there any bug in 2.4.0 kernel when the function is called. Can anyone help me to resolve the problem. Regards Shiju - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org
