[SOLVED] Issue with BCM57840 on ProxMox 5.2

[Ilmir M]

Good day!
I have some issue with 10G network adapter (ASUS peb-10g/57840-2t) with IBM x3755m3 server based on Opteron 6220

> dmesg | grep bnx2x
[ 2.015111] bnx2x: QLogic 5771x/578xx 10/20-Gigabit Ethernet Driver bnx2x 1.712.30-0 (2014/02/10)

This card have two 10GBase-T ports

I thought that it is hardware problem, but when I try Fedora 28 Live CD the bnx2x module loaded without error and it is working fine.
Fedora's output

The difference between this Linuxes is kernel version:
Fedora - 4.16.3
Proxmox - 4.15.17

What is the best solution in this situation?

 

[Ilmir M]

Solved.
It's problem with memory mapping conflict between root pci-e and pci-e network card.
Kernel boot parameters changed to pci=realloc=off.

how did you add this to the kernel boot parameters? sorry might be a silly question #newbiehere

See the documentation: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#sysboot_edit_kernel_cmdline

I think I might need to add the option in /etc/kernel/cmdline will try that.
