Hi,

Good news - I have success!

The problem is definitely with the interrupts.  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.
