[OpenAFS-devel] reproducible failure with recent changes to i386_linux*

[Neulinger, Nathan R.]

If I back off all the patches to the afs/LINUX directory since Jan 10th,
everything is happy. As soon as I re-apply them, afsd will still start up
ok, but it's hosed. I get segfaults ls'ing /afs, etc. 

I'm going to try incrementally applying some of those patches and see what
happens.
