However, as of utopic, this property is not being inherited by downstream devices. Specifically, the xgene-pcie device is marked as coherent, but the devices behind it (mellanox card) still get initialized with non- coherent ops. This results in the mlx4 driver bailing out with the following messages: [ 18.703635] mlx4_core 0000:01:00.0: command 0x23 timed out (go bit not cleared) [ 18.710911] mlx4_core 0000:01:00.0: Failed to initialize queue pair table, aborting There's an upstream discussion on the topic here: http://www.spinics.net/lists/arm-kernel/msg362320.html To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/debian-installer/+bug/1386490/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
