I have had one solid lockup in the i386<->i386 case during heavy NFS writes while moving large files (ISO images of CDs) back to the server after upgrading to 5.0 (client was also 5.0). I didn't have a debugger in the kernel at the time, and haven't reproduced it since I put it in to get a back trace/dump (~2 weeks now). I was waiting to post on the topic until I had some data to provide useful debugging, and to make sure it wasn't a fluke (new hardware, as well). I'll let the lists know if I see this again. > Hi, > > I experienced an NFS problem between an i386 box and a sparc64 box. > The i386 box that is running 5-CURRENT as of Mar 7 acts as an NFS server, > and the sparc64 box that is running 5-CURRENT as of Mar 5 acts > as an NFS client.
