Series of strange PCIe and HDMI errors appearing on Blade 3 node

I’ve received a bunch of error messages appearing on one of my Blade 3 nodes of my Cluster Box. I’ve got one of your official Debian Bookworm images running on that node:

root@blade3:/# uname -a
Linux blade3 6.1.99 #2 SMP Thu May 22 22:47:17 CST 2025 aarch64 GNU/Linux

Just after booting, I get this error list in the syslog:

Is this a serious failure? And: What can I do to get rid of this?
