I can't easilly do this - it's a production box and they won't afford me
the dowtime. I'll try the latest patches against a 2.4.21 kernel (but I'm
not sure if I need the AC patches or not with .21, I'll need to check - I
needed an AC-1 patch for 2.4.20 to get the Promise IDE controllers to
work) Otherwise, it's back to ext2 for this. It ran solidly with ext2 and
2.4.20-ac1 for about 6 months before I tried XFS, and the only thing thats
changed is the kernel.
