Mike, et al,
I rebuilt the kernel w/o suspend-on-halt, and there was no change in the
behavior. The odd part about this is that the machine functions normally
in all other respects. Not that this is a scientific benchmark, but a
full kernel build of 2.1..65 runs a bit under 10-minutes - certainly not
indicative of long dead periods.
I'll re-test again under 2.0.32 this evening, though I believe I've
already tried this without seeing the problem..
