Public bug reported:

[Impact]
On Ubuntu, it gets the error of "Device or resource busy."

fuser shows that the kernel thread "kdevtmpfs" is occupying the HBMs.

I tried to build a kernel without CONFIG_DEVTMPFS set.
But it got stuck in initramfs

If it is possible, please get this issue a quick triage,
just to get a basic estimate how hard this issue is and
how much effort is needed for Ubuntu for support it.
