How do I lower a > kernel thread's priority so that it is periodically preempted? Kernel threads are not pre-empted in 2.2. It takes extra patches to make them pre-emptible in 2.4. It is a config option to allow pre-emption of kernel threads in 2.5. Call schedule() periodically or do something similar. -- http://www.wirex.com/
