maybe offtop but in my opinion we need more info about when it will be crash ? It will be when some operation or else ? Need more info
can you elaborate more on the crash scenario? what was the last action/s that triggered the crash?
was it during installation of Mellanox Driver for FreeBSD?
Have you followed the instruction of "Mellanox OFED for FreeBSD for ConnectX-4 User Manual"?
Were the proper kernel sources installed on the server?
Have you loaded mlx5, linuxapi, then compile and install linuxapi module under /sys/modules/linuxapi.?
Panic/crash may occur when creating/destroying a VLAN in a loop during traffic
Review the pdf above, ensure you've installed all as recommended and if it keeps crashing - open a support ticket to support.mellanox.com and provide full dumps fro troubleshooting the case
I use FreeBSD-11 with Mellanox in /usr/src/sys
they are very similar to what is on your site, I beleive they are just the same
yes, I load mlx5.
configuration is (rc.conf)
cloned_interfaces="lagg0 vlan200 vlan227"
ifconfig_lagg0="laggproto failover laggport mce0 laggport mce1"
ifconfig_vlan200="vlan 200 vlandev lagg0 X.X.X.X netmask 255.255.255.0"
ifconfig_vlan200_alias0="vhid 20 pass pass20 X.X.X.Y/32"
if I do not use CARP, it is ok
as for crash, if you can see on the attached screenshot, crash is not saved as a dump
