Motherboard BMC Remote Control

[mwalton4uk]

Hi all,

I'm seeking assistance with my latest Proxmox home lab server setup.

I've gone with an AMD Threadripper Pro 5955 and the ASUS Pro WS WRX80 motherboard (if it matters, OS is installed a ZFS Mirror). One of the key benefits of this board—alongside its seven x16 PCIe slots—is the onboard BMC/IPMI with iKVM, which is especially useful since the CPU and board lack onboard graphics.

The remote control feature via IPMI works well initially, allowing access to BIOS and selecting the image to boot into etc. However, after botting into Proxmox, the iKVM display freezes during boot after the following messages on screen:

EFI stub: Loaded initrd from LINUX_EFI_INITRD_MEDIA_GUID device path
EFI stub: Measured initrd data into PCR 9

As a temporary workaround, I’ve installed a dedicated GPU for console access. But eventually, I plan to pass that GPU through to a VM—meaning I’ll lose terminal access in cases where the network fails or the system doesn’t boot correctly.

Has anyone encountered this issue or found a fix to prevent the BMC/iKVM remote display from freezing during Proxmox boot?

Thanks in advance!

I don't think it's freezing, it just wont output something. You may log into the PVE node after this "freezing" and check dmesg what graphical console was detected and what happend to it. Sometimes, if you have more than one output (e.g. VGA and HDMI), it just uses the wrong one, so maybe this is also here the case?
