Hi Ben, thanks for your replay. I thought there was an upstream fix due to this answer from Andy Gospodarek (Comment 30 in the Red Hat bug report). https://bugzilla.redhat.com/show_bug.cgi?id=640026 They increased the ring buffer size as far as I understand. [...] They increased the maximum allowed RX descriptor ring size. You should first try changing the value to the current maximum yourself, with ethtool -C. Ok, thanks for the hint with ethtool -G, I will try to increase the RX value from 255 to the maximum of 1020. Just for info: increasing the RX descriptor ring size to 1020 probably fixed this issue, they was no further incident so far. Thanks for the hint, kind regards, Joerg. -- To UNSUBSCRIBE, email to debian-kernel-requ...@lists.debian.org with a subject of unsubscribe. Trouble?
