[Crash-utility] Finding thread/task idle time

Hi all - When looking at a vmcore, is there anyway to determine how long a thread has been idle ? When debugging hangs, it would be very important to know this....if example, if a thread is blocked in biowait()/submit_bio() for more than a few milliseconds. Any insight appreciated....An example would be ideal. Thanks in advance, Nipul -- ------------ Nipul Gandhi x1306 VERITAS
