Comment on How to disable ACPI on productive Linux servers to decrease kernel panics and increase CPU fan lifespan by admin.
Hi,
There are plenty of complains from old mailing lists. ACPI Support has never been too good in Free Software realm (as far as I know). On servers I really doubt what would be the purpose of just one another piece of memory pre-loaded software, which every now and then makes the server fan to change rotation cycles. Imagine you’re running a webserver and it is very loaded sometimes, and sometimes the load drops, imagine this happens frequently, in situation like this I’m quite sure ACPI will make the fan cool less at points and therefore on high loads it will be easier for server to be overloaded due to overheat. Maybe my logic is wrong somewhere, but this is how I think. Besides that I don’t think disabling ACPI will increate oseverall heat? Why would that be? Maybe you’re right, pls explain why would disabling acpi increase heat?

Hi Willbert,
Try to disable ACPI support on BIOS level and see if it helps. I hope this solves it. Otherwise you can try to also disable any loaded modules in kernel related to ACPI, I guess one of this 2 might solve your situation. Also if you have some embedded sound card / modem or whatever you don’t need on system make sure you disable it from BIOS.

Hi thanks for saying I didn’t know. I removed the logo from Tux. Hope now it is ok.
Thanks for the info good to know. But still I think at some cases, it might be useful to disable ACPI 🙂
Now Suse is also using yum like in Redhat based distros and no longer uses yast?
Best

Hi Stan,
I guess you cannot read the writtings on the icon as it is in cyrillic.
This is not Saint Mary and Saint Peter but Adam and Eve written in cyrillic on top of the icon.
Actually in orthodoxy it is a requirement for the depicted personalities, especially saints to have
written on the names of the saint and have the Halo. If you look closely at the picture you will notice
the two Adam and Eve are missing a Halo. The only person with a Halo in the icon is Saint John the Baptist.

–rwo, –report-warnings-only
This option causes only warning messages to be displayed. This can be useful when rkhunter is run via cron. Other options may
be used to force other items of information to be displayed.
–sk, –skip-keypress
When the –check command option is used, after certain sections of tests, the user will be prompted to press the return key
in order to continue. This option disables that feature, and rkhunter will run until all the tests have completed.

As rkhunter check, can be pretty annoying and ask you to press keypresses multiple times and spit you a lot of unnecessery data a very good useful option arguments are:
–rwo and –sk
# rkhunter -c –rwo –sk
Warning: The SSH and rkhunter configuration options should be the same:
SSH configuration option 'PermitRootLogin': yes
Rkhunter configuration option 'ALLOW_SSH_ROOT_USER': no
