But it didn't crash like the Nocona machine. Ah thanks. Sorry I have a very busy day at work and am unable to do anything about it till tonight. I could imagine on nocona this would be due to the idle task being scheduled on init - which it is not supposed to do but if you read the comment in sched_init it says it *might. I have no way of handling that at the moment because I wasn't sure it ever happened any more. As for the powerpc.. I have no idea (from where I am at the moment which it would be totally inappopriate for me to try to debug :P), sorry. -- -ck
