Hi Emeric,

Thanks for the detailed logs.
You may refer to Romeo's issue:
http://permalink.gmane.org/gmane.linux.network/309587

There's this stable fix for the (older) TSEC controllers:
commit 5eaedf31319d5f80eaaee1eec8dd18c0b452f0d1
("gianfar: Add backwards compatible Single Queue mode polling")

that for some reason was not included in kernel 3.10
(but it was included in kernel 3.11).

Hi David,
Can we have this gianfar fix included in kernel 3.10 as well?
Is there anything I can do to help with this?

Thanks and regards,
Claudiu
