Interesting. This weighs against the hypothesis of a hardware problem (device monopolizing the PCI bus, for example). Even 3 ms after FSBR was turned on the system was still operational.
This might be a stupid question, but what else can happen during this time? Now that you've set this in the uhci, do other threads/processes have access to it? Is it that other URB's are being processed and so see the newly updated state of the uhci?
You need more than code documentation; you need to understand how UHCI controllers work! It doesn't change how the code runs at all -- it changes how the controller behaves.
Isn't the controller just code, so changing how it behaves means the code is running differently with fsbr set?
