Howdy,
Well, I *think* that 1.08 has reduced the number of crashes we've
had in the field with customer prem equipment, but it does still occur for
some customers. I've noticed that those customers who *never* have this
type of problem, are those who use UPS's, and we always hook up to it if
one is present and available.
I was reading a recent issue of embedded systems programming
recently and it was discussing power-on-reset circuits. Not your avarage
run of the mill subject, but the gist is that when most cpu type devices
power on, they need a certain hold time to ensure that everything
stabilizes before the processor attempts to start using the bus and
otherwise functioning. Failure to observe these hold times will result in
an apparently crashed system if it tries to come up while the system
isn't ready. So I'm wondering if some of the lockups I've
observed are the result of an airbridge reset - induced perhaps by a power
sag or other condition - that brings the hardware down, but fails to also
bring the cpu all the way down and back to it's initialization state.
Just my $0.02.
