Hello, I am a new user, and recently installed without problems. After installation, I added a Broadcom 4 port NIC, and rebooted. It picked up all the ports. I then added a port to vmbro, and got hung up on reboot. It froze at /dev/mapper/pve-root:clean

I then entered the card configuration from POST, and disabled SR-VIO, shich did nothing

I then tried doing a fresh install with the NIC in place. It locked up at searching for DHCP.

Then removed the card and it now will reboot into the initial installation.

Is there a fix for this, or should I hunt for another card. I have a Mellanox in another machine that gives no problems
 
First you should update the firmware of your nic.

Then you could try in the POST config of the nic to disable RDMA if your card supports it.
Or disable the broadcom rdma kernel module.
Code:
echo "blacklist bnxt_re" >> /etc/modprobe.d/blacklist-bnxt_re.conf
update-initramfs -u

Except for older firmware or RDMA enabled there *should* be no major issues with broadcom nic's on PVE.
