Hi....Since my last posting, I have reloaded my machine with FC3 + all the latest YUM updates, and I have built the latest 2.6.12-rc5-mm2 + NFS CacheFS patches. However, I am still having the same problem. I have attached the process backtrace below.....to my untrained eyes, it looks the same as the ones in my
previous posts.I also tried using NFS + CacheFS using a loopback filesystem. I got further with this....I was able to mount my NFS filesystem and cd into the filesystem tree. I was even able to 'cat' a few small files, but when I tried to transfer a large file the kernel itself crashed.....I have attached the output from this below
also.I am really interested in trying to use this and am happy to help get this to work for the benefit of everyone, although I am not a kernel programmer so I am not sure how much I can help except to
provide feedback from testing.Could anyone recommend a Linux distribution on which they have gotten this to work?
Has anyone got this to work on FC2 or FC3?Finally, I have attached my kernel .config in case there is something I did wrong when building the
kernel. I'd be really grateful for any help or suggestions on what to try next. Chris.
