Did you try removing them immediately, and find some problem? I've never been sure how that hardware schedule caching thing is supposed to work. Ideally it would only apply to (s)ITDs that were active, and only to the fields used to perform the data transfer ... rather than the schedule tree itself. If it cached the tree (pointers to next (s)ITD or QH) that could be trouble; ditto caching records for "expired" descriptors. - Dave ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
