When you're done entering text, push the Escape key this will put you in command mode. Now, you can enter text as in a "normal" editor, and pressing the ENTER key will terminate the actual line and place the cursor at the beginning ofĪ new one. First of all, you'll have to push the Insert key, because vi, no idea why, starts Here, what you need to know toĬreate the blacklist file. You must have a basic knowledge concerning the vi editor to be able to use it. Makes you superuser, the second one creates and opens the file): Being in the directory /etc/modprobe.d, enter the following two commands (the first one In a terminal, you can do this using the vi editor. Thus, we'll have to create a new file, called nf in the /etc/modprobe.d directory. In fact, on CentOS, there usually is a separate configuration file forĮach module of the blacklist. On my system, there is a fileĬalled nf, that seems to be specific for the dccp module. However, if you have a look at the directory /etc/modprobe.d, you will find no file called nf. The procedure to fix the error is the same as on Linux Mint: 1. The second error message concerns the SMBus issue on VMware,Īs detailed for Linux Mint at the beginning of this tutorial. (even though I think that there is a way to update the list of certified hardware). Anyway, this is a message that you can really ignore Rather new and includes a rather recent CPU, this must not surprise (CentOS 7 is not the latest version of the OS). This processor is not certified by Red Hat, or more correctly has not been certified by Red Hat when CentOS 7 was released. The first one concerns the CPU of my computer that is said "not having undergone upstream testing". There are actually two (non-related) issues here. The screenshot below shows the messages, that I got when booting CentOS 7, running on a VMware virtual machine. Please, note that you have to reboot to make your changes become active.įixing "SMBus Host Controller not enabled" on CentOS. Mint), this may be done by running the command In fact, we'll have to regenerate initramfs. This is not true: Even after having made the changes to nf, Linux Mint will display On some pages, you can find on the web, you are told that that's it. User, you have to use the Save As command to save it to your home directory and then, in a terminal, copy it as superuser to /etc/modprobe.d: If, as on the screenshot, you have opened it as a standard If you have opened the file as root (what is possible on Linux Mint), you can save (rewrite) it directly. The SMBus module is called i2c-piix4 and we can prevent it to be loaded by adding the following line at the end of nf: Of this file, opened in the Linux Mint default editor, on my machine. This file is often (and it's actually the case on Linux Mint) called nf (some Linuxĭistributions use a somewhat different name on OpenSuse, for example, it's called nf). Here we'll find a configuration file containing a blacklist of those To take a look in the directory /etc/modprobe.d. To prevent our module to be loaded, we have On Linux operating systems, a major part of functionality is defined by configuration files located in the /etc directory. So, fixing the issue should not be too difficult: All we have to do is to prevent the module to be loaded. The error is due to the fact that VMware doesn't actually provide that level interface for CPU access, but some Linux distributions (perhapsĮven most of them) try to load the corresponding kernel module anyway. Limited number of error messages when problems occur. The SMBus monitors voltage and temperature and can send a Interface that allows system and power-related components to communicate with other parts of the computer. The SM Bus Controller, also known as the SMBus or System Management Bus, is a chipset within a personal computer that provides a two-wire What does not mean that fixing it wouldn't have any The important first: There is no reason to worry: you can safely ignore this error.
