I believe so, yes, if my recollection from earlier in the month is correct. Without it, the problem doesn't exist, but the requeueing doesn't happen either (well technically according to the code it does, but it doesn't do anything) - so whether that's the problem or whether it simply MASKS the problem I can't say without further investigation. I am loading up my sandbox machine with an exact copy now, and expect to know more sometime tomorrow - I will have to go through a full buildworld/installworld/buildkernel/installkernel to bring the sandbox up to date and then stuff a SATA disk and adapter in there to re-create the environment closely enough to be sure that I'm looking at the same issue. More as soon as I know with certainty. -- -- Karl Denninger (karl@denninger.net) Internet Consultant & Kids Rights Activist http://www.denninger.net My home on the net - links to everything I do! http://scubaforum.org Your UNCENSORED place to talk about DIVING! http://www.spamcuda.net SPAM FREE mailboxes - FREE FOR A LIMITED TIME! http://genesis3.blogspot.com Musings Of A Sentient Mind
