Hi. I've upgraded CURRENT from December 19 (https://github.com/freebsd/freebsd/commit/fd53ccf393f4f8ac1948e97eca108) to today (https://github.com/freebsd/freebsd/commit/391a83c86bb91ae3840cf37b7de478f42cc97e2a) and my Mellanox ConnectX-2 network card stopped working: mlx4_core0: <mlx4_core> mem 0xfe100000-0xfe1fffff,0xf0800000-0xf0ffffff irq 32 at device 0.0 on pci7 mlx4_core: Mellanox ConnectX core driver v3.4.1 (October 2017) mlx4_core: Initializing mlx4_core mlx4_core0: command 0xffa failed: fw status = 0x1 mlx4_core0: Failed to map EQ context memory, aborting device_attach: mlx4_core0 attach returned 12 Loading the OLD mlx4.ko and mlx4en.ko on the NEW kernel actually does work fine! Reverting all mlx4 changes between then and now (no big changes, mostly just the 1 << 31 thing from D13858) and rebuilding the mlx4 module with CC=clang50 does not help. What happened?!
