There might be fixes in the -ac tree that effect my problem -- I'll try
the latest -ac and see what happens. Thanks for the suggestion.
But the distributions use _the_ kernel. Even if -ac is fixed, it's not
really something I would be willing to put in production. Until I found
the noapic work-around, we were basically going to have to move off of
Linux. I could very well be an isolated case, but the APIC issues I'm
seeing scare me, and not just for my sake.
I mean all of this in the utmost respect -- I just felt that this issue
needs a little more light shed on it, and I'm here to help in any way I
can.
