Darn it, how do I find out what in the #$%@ World are those

waiting for? :(
They're waiting for Godot? :-) I don't have any processes in this
state on the Linux boxes here. How do these processes look in the
output from "ps auxw"? If not ps, which tool are you using that tells
you a process is waiting? Almost every process in the output from ps
auxw should show S (sleeping) and 1 or 2 should be in R (running).
My guess based on nothing is that you have the ACPI stuff turned on
My 'knowledge' stands that ACPI ON is 'good', isn't it? Can you
elaborate? There are no laptops involved, so I certainly don't need
'power management features enabled'
ACPI, when it works properly, is something you want to have on. You
probably *do* want power management features if only so that your CPUs
can throttle themselves back to 1/3 max speed when they're not needed
and thus keep your electric bill lower.
