Does anyone know if there's a way to automatically log the time ( or anything ) when I get the "PCI Capacity Limit Reached" message?
I'd like to find out what process is happening on my computer when that happens.
I've already done the things in the manual, and deleted the shared USB controller like garyb suggested. Those things helped!
The only Scope prob I've got, is an occasional interruption from this message. It happens about the same amount when I'm not doing anything on the computer.
I do have internet on it - maybe I should try disabling that.
PCI Capacity Limit Reached - loggable?

Use the DPC Latency checker to see if something is polling your bus periodically and incurring a massive latency penalty.

Bingo!
I ran that app, and it showed a few of the red bars going by, and a few yellow ones. Green ones were a little tall. So I disabled my Linksys wireless adapter, and voila, the graph looked very smooth, just low-green ones.
When I enabled the adapter again, I immediately got the PCI Capacity Limit error message.
Thanks!
Now what; move the internet to my other computer or something, I guess.

It's funny I almost suggested wireless in my last post as it's a well-known issue with wireless cards. Part of the issue is using WPA-2 encryption (which you should do) as most cards just use the system's CPU to encrypt/decrypt each packet.
The solution imo is either use ethernet/a non-wireless adapter or try to find another wireless card that has better drivers and can offload tcp processing & wireless encryption. I have dual onboard Intel gigabit adapters connected to my network and can get down to 0.7ms latency on my main machine using my RME's drivers without any dropouts, though the cpu does rise as you'd expect (I won't be mixing 128 tracks at that latency.) This is an upmarket board so the ethernet is a server chipset that actually does offload tcp processing as well to some degree.
Basically this is my way of saying that I really don't see much need to keep my music machine 'isolated' these days just for the sake of it, nor do I do any exotic OS tuning anymore beyond disabling some unnecessary services (I loathe system restore).

An external wireless access point is also a good option - picks up wireless and connects to ethernet. I'm using a Netgear WG602, seems to work well.

Proxim/Orinoco make a USB external one we use here at work..Good Range & stable.
