System is diskless multimedia terminal (minimyth).
Issue is: dead Eth port after series of S3 suspend-resume (10-50 cycles) when NFS is used as share.
With CIFS all looks OK.
220.127.116.11 works OK (700 cycles tested)
I applied patch for bug 11156 as without it system randomly hangs at resume stage.

If everything is correct with CIFS, I guess the problem is somehow related to NFS.
Can you confirm that we understand?
CIFS is okay, and NFS is failing, and thus the network interface is
okay and the issues is specific to NFS?
I have following results for 18.104.22.168.
System is disk/kbd-less network booted appliance so I can control it only by: IR (lirc), VNC and telnet.
CIFS: 500 S3 cycles: OK
-no 11156patch: random hang on S3 resume (black screen, Eth dead)
-with 11156patch: no Eth after 1-40 S3 cycles, but rest seems to be fully functional.
Exactly the same system but with 22.214.171.124+patch11156 - S3 with CIFS/NFS are OK
Is this still a problem on current kernels?
It looks that with 2.6.33 and newer all is OK, albeit I'm not able to tell whivh kernel verssion fixed problem.
I'm closing this as unreproducible then, thanks.
If this pops up again, please reopen.
