[OpenAFS] file corruption redux

OK, by replacing a RAID controller and memory, I've managed to modify the 
behaviour of my little file corruption issue, but magically it remains. Now it 
seems to be isolated to the client side -- I have yet to find a bad md4sum of a 
file on the server. The client-side corruption also comes and goes -- with a 
well-placed fs flush or flushvol, it's gone, only to reappear later. I've 
verified that it happens on 1.4.1 and 1.3.86 (I don't have any 1.2.x clients 
left to try, but I can open up the volume to the world if anybody wants to 
try).

cmp -l on a bad client-side file and known good file doesn't enlighten me, but 
maybe it will for somebody else:

cmp -l aspell-pl-0.51-3.i386.rpm /tmp/aspell-pl-0.51-3.i386.rpm
13468782 337 317
cmp -l eclipse-platform-3.1.0_fc-0.M6.22.i386.rpm /tmp/eclipse-platform-3.1.0_fc-0.M6.22.i386.rpm
 2883589 357 257

I can do whatever debugging will help on the file server, as it has exactly one 
volume on it right now.
