Neither of you have said what architecture you're talking about, so I'll 
assume it's probably i386.  So far most of my 2.6 work has been on amd64, 
but I do have an i386 machine that's been running 2.6.6 for months without 
problems.  I can try to reproduce this, but it would be helpful if you 
could provide some additional information.

If this is a kernel you built yourself from the kernel.org sources, it 
would be very helpful to have a copy of the .config file from the kernel 
source tree.  Hopefully that will enable me to track down what setting you 
have enabled that is triggering the problem.

If you got the kernel from a distribution, I need to know exactly what 
package and version you used, so I can go find the same sources and 
configuration that were used to build your kernel.  Often distribution 
vendors add a variety of patches of their own, and sometimes these change 
things that we're depending on.

You said you observed this problem running OpenAFS-1.3.73.
If possible, it would be helpful to know if you can reproduce the problem 
with the current CVS version.
