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?!
Hi,
Can you do:
objdump -Dx /boot/kernel/mlx4.ko > mlx4.ko.txt
objdump -Dx /boot/kernel/mlx4en.ko > mlx4en.ko.txt
And diff the text result between working and non-working ko's.
Can you also make sure that /boot/modules does not contain anything *mlx4* ?
