Properly blacklisting a module?

Asked by Torsten Spindler

For getting suspend (S3) and resume to work on my laptop I need to unload the ehci_hcd module. I can add it to SUSPEND_MODULES in /usr/lib/pm-utils and it works. Is there a cleaner solution? Configuring this in /usr/lib does not look right to me.

Hello:

You can add its name to the /etc/modprobe.d/blacklist file.

For more info on the init.d structure check this out:

This will remove the module from the system completely, I only want to unload when suspending to RAM.

Thanks, but my question is specific to the pm-utils package and not a general problem with suspend and resume.

Opensuse wiki provides a good explanation of pm-utils:
http://en.opensuse.org/Pm-utils#Configuration
There is information about unloading modules before suspend.

Alternatively addding the module name to the MODULES= line of /etc/default/acpi-support should work instead.
