It appears suspending the laptop and then waking it up kills the USB

How fix?
I thought it was pretty common knowledge that suspending Linux can screw
up all kinds of things, including the clock and serial mice.
I always turn that and its cousin, power management, off in the bios. Am I
wrong?
I'd say, generally speaking, yes. Turn on ACPI and turn off AMD unless
you have a really old motherboard that does not support (well) ACPI.
ACPI and AMD don't play nice together.
For instance, I found on an previously mentioned Tecra 8000 that had
problems without ACPI, that if I used "acpi=force" it was able to load
the OPL3 sound drivers.
The expedient fix was to move from FC6 to F7. There have been vast
improvements in ACPI, mostly aimed at laptops, in the last year. And it
looks like F7 has a lot more of them than FC6.
Still lots of work to be done, since the attitude of some top Linux devs
is that the ACPI spec seems to be a horribly written and widely
inconsistently adhered-to spec in dire need of replacement with
something more sane. Still, at the moment, it's better than any
alternatives. Of which there seems to be none.
