Hello Everybody,

my name is Dario. I write here a little for support and a little for leaving a 
trace for others with the same my problem.

I manage a server providing various services, between them is tftpd. The 
service is mainly used for storing configurations and operating systems for 
routers.

I was perfectly working with kernel-2.6.32-131.21.1.el6.x86_64.

After upgrading to last kernel version (2.6.32-220.2.1.el6.x86_64) I was not 
able anymore to read and write files (through tftp protocol). No other 
malfunctions came to my eyes. I tried, unsuccessfully, many ways to 
investigate a possible changed behavior (but the tftp server was not changed, 
so no connection was possible).

At the end I installed the previous kernel version, which corrected the 
problem.

Any suggestion on how to signal this problem to developers would be really 
appreciated.

Thanks for your kind cooperation

Best regards and wishes for new year

Dario
