[OpenAFS] Problem with 1.3.81 on kernel-2.6.11-1.14

[William John Murray]

  Hello there,
             I see different symptoms from the osi_cache problem above. 
I am using
1.3.81 on Fedora Core 3, kernel 2.6.11-1.14 Disk is ext3, the ntfs 
driver is also loaded.
I start afs fine, but the first 'ls' freezes the system entirely. There 
is nothing
in the log.
   If I start AFS and then shutdown, I get a more helpful crash from 
'umount'
Last line is:
<0>Kernel panic - not syncing: fs/fs-writeback.c:96: 
spin_lock(fs/inode.c:c03c01b0) already lockedby lib/dec_and_lock.c/32. 
(Tainted: P     )

I applied the patch for osi_cache, but it seems irrelevant.
   Any ideas, anyone?
        Bill
