>Description:
I'm mounting a remote file system sitting in an IBM 530 Powerserver
running AIX 3.2.5.
When copying files from a local file system to the remote file system,
or when copying from the remote file system to the remote file system, 
the copy hangs after a few fragments have been transmitted (I verified
this using tcpdump). I never had this problem with 2.1 RELEASE, and again
the problem doesn't occur with 3.0-SNAP
>How-To-Repeat:
mount -t nfs remote_machine:/remote_directory /mnt
cp /local_directory/file /mnt
>Fix:
I would like to know the fix.

 This is probably fixed in 2.2.2-RELEASE.  Please re-test on that version,
 thanks.

 When I read that the problem might be caused by a fast server
 overwhelming a slower client, I did the following to prevent IP
 fragmentation:
 
 mount -t nfs -o -r=1024 remote_machine:/remote_directory  /mnt
 
 Then  I did
 
 	cp /mnt/remote_file local_file
 
 and after a few seconds I started to get kernel panics ! (Page faults
 while in kernel mode, LRU queue inconsistent, and other nasty messages).
 
 By the way, the client's network card is AMD PCNET (pci & isa), 
 at least this is what Win95 reports.

 Ouch!  It certainly shouldn't do that.  Can you copy down the information
 that the kernel prints on the panic and send it to me along with the part
 of 'nm -n /kernel' which contains the instruction pointer where it
 faulted.

 I tried 2.2.5-BETA to see if my problem had been solved, but the problem
 is still there. However, 3.0-970909-SNAP works fine. Letting u know just
 in case that might trigger some ideas as to what's causing the problem,
 and perhaps having it fixed in time for 2.2.5-RELEASE. :)
