I saw nothing for bge in vmstat with MSI enabled. Rebooting with MSI disabled and all works well so far - I haven't done a lot of testing yet, but it has been operating with pings / file transfers for over 1 hour now without problems. Apologies for asking such a basic question, but I've typically downloaded latest sources etc. from HEAD via cvsweb in the past when I needed them. How do I locate the r219737 and r219740 changes on their own to try them out with MSI enabled? I'm guessing I'll need to cvsup the relevant sources but I can't see how to find out what I need. Thanks, Paul.
