following is my test cese,
a nfs server server with ar8131chip, device id 1063. export /tmp/ dir as the nfs share directory,
the client, mount the server_ip:/tmp to local dir /mnt/nfs, ust a python script to write and read data on the
/mnt/nfs/testnfs.log. it works fine.
Can you give me some advice on how to reproduce this bug??
Best wishes
