[PATCH] IPMI: use schedule in kthread
Corey Minyard <minyard@acm.org> The kthread used to speed up polling for IPMI was using udelay in its busy-wait polling loop when the lower-level state machine told it to do a short delay. This just used CPU and didn't help scheduling, thus causing bad problems with other tasks. Call schedule() instead.
