I repeated my tests again with a build from half an hour ago, once on 
SMP, once with kern.smp.disabled=1. Nothing changed: Copying a 2162 
bytes file works fine, copying a 256004096 bytes file locks afs. cmdebug 
does not return anything.

Trying to reboot, I get "init: some processes would not die; ps axl 
advised". After "All buffers synced", afs got a message for me:

afs: WARM shutting down of: CB... afs... BkG... CTrunc... AFSDB... 
RxEvent... UnmaskRxkSignals... RxListener... osi_StopListener: 
rxk.ListenerPid ffffff0071a9c000 {2nd try: ffffff005cf3460}
WARNING: not all blocks freed: large 0 small 1
  All allocated tables... done

Nothing new, unfortunately.

I could try different file sizes... maybe around the cache size -- would 
that be interesting? (I have "/afs:/var/openafs/cache:100000" in 
/usr/local/etc/openafs/cacheinfo. That is in KB, isn't it?)

Cheers,
Jan Henrik
