Troubleshooting Intel VMD Driver Boot Issue on Supermicro Server with Rocky Linux 8.7

I was installing Rocky Linux 8.7 on a Supermicro Server with Intel VirtualRAID. I could not boot to Rocky Linux 8.7, the Install Screen could not be presented. Instead, there are repeated errors like the one below on the screen.

“DMAR: [INTR-REMAP] Request device [bc:00.5] fault index 0x8000 [fault reason 0x25] Blocked a compatibility format interrupt request”

The Issue was explained in the Article from Intel “Unable to Boot RHEL* 8.7/9.0 if Intel® VMD Is Enabled for Intel® Virtual RAID on CPU (Intel® VROC) RAID Management”

Resolution
A problem with the inbox Intel®️ VMD driver included in RHEL 8.7 and 9.0 was identified, and it is necessary to add the boot parameter intremap=off to the kernel command line while installing the operating system. This will prevent the operating system from encountering any problems.

This particular issue has been fixed via a kernel update and has been implemented in RHEL 9.1.

it is necessary to add the boot parameter intremap=off to the kernel command line while installing the operating system

I tried Rocky Linux 8.9 and the issue was fixed.

How to Install Rustup for All Linux Users in a Cluster or Shared Environment

Rustup is an installer for System Programming Language Rust. If you are running the installer script for yourself, you can take a look at https://github.com/vi/rustup

# curl -sf https://static.rust-lang.org/rustup.sh | sudo sh

But what if you have to install for all users in a Cluster or Shared Environment, how do we do it? Fortunately, we have good information that is found at Installing rustup for all linux users . I took some snipplets from that site

In that article, the author recommends to define RUSTUP_HOME and CARGO_HOME

# export RUSTUP_HOME=/usr/local/rust
# export CARGO_HOME=/usr/local/rust
# curl https://sh.rustup.rs -sSf | sh -s -- -y --no-modify-path

The directory should be installed at /usr/local/rust/toolchains/stable-x86_64-unknown-linux-gnu

# ls -l /usr/local/rust/toolchains/stable-x86_64-unknown-linux-gnu
