what afs options are you using?  -dynroot? -fakestat?  approximately how
long is some time?

you dont mention the machine platform, but i am going to guess x86_64?
it would be helpful if you could do something like:

gdb /wherever/the/afs/module/is.ko
(gdb) info line *afs_linux_getattr+0x288

and send along the output.  thanks.
