One way to do this is to copy a file from one nfs mounted directory to another. It dose not happen on the same mount and not when copying from nfs to a local disk. To make this even more complex it works with cp and mv but not in mc(midnight commander F6 ). The nfs mounts is from the same server and same disk on that server, mounted using automount. linux version is client 2.4.19-pre9 server 2.4.19-pre8 using reiserfs on a raid1 partition. here is a calltrace on mc when it is dead. Trace; c0129875 <__lock_page+a1/c8> Trace; c01298b1 Trace; c0129faa Trace; c012a466 Trace; c012a360 Trace; c0173a2d Trace; c01372f7 Trace; c01088cb The nfs mount is unusable after this. Every process that uses it enters D state. I have attached a strace of mc when moving file /home/ken/3 to /delta/kernel/ mc 4.5.55 And now to something completely different. (please forward to gconf people) I also found what I would call a serious problem with gconf during the testing. It goes something like this. 1. have homedir on nfs 2. pull network cable when gconf app active(nautilus, galeon ..) 3. Shutdown 4. insert network cable. restart 5. watch all gconf apps fail to start. gconf 1.0.9 --=-Q+xKZzlL4wxfemWx3rOB Content-Disposition: attachment; filename=mc.log Content-Transfer-Encoding:
