I have a Dell laptop running Debian Sid. Current kernel (4.15.4) is configured to load dell_smbios as module (CONFIG_DELL_SMBIOS=m). This produces the followning error while booting

dell_smbios: No dell-smbios drivers are loaded

I want to add a kernel boot parameter to stop dell-smbios from being loaded. Something like dell_smbios=off (Used to diable ACPI, i.e acpi=off) or dell_smbios.disable=1 (Used to disable IPv6, i.e ipv6.disable=1).

So how do I know the specific kernel boot parameter for a given configuration option in the config file in /boot directory?

  • Try adding `modprobe.blacklist=dell_smbios` or `module_blacklist=dell_smbios` as boot parameter. – don_crissti Mar 04 '18 at 15:54
  • Just because the option is selected to configure a driver as a module does not necessarily mean it is being loaded. In fact, the error message seems to suggest to me that the module is, in fact, *not* being loaded ("no drivers are loaded"). I think the problem needs to be clarified: is the module being loaded when it shouldn't be, or is it not being loaded, when it should? – Time4Tea Feb 12 '19 at 17:01
  • Is it causing any actual problems, once the system is up and running, aside from the boot log message? – Time4Tea Feb 12 '19 at 17:57
  • @Time4Tea Yes exactly -- I can `modprobe i915` any time I have realized. I do NOT get a "warning" when I boot without, but that actually wouldn't be wrong when I see the importance of this (intel-) GPU/DRM module. Probably that Dell-SMB module is also a bit special. –  Oct 18 '19 at 06:54

Since it’s configured as a module, you should blacklist it. To do so, create a file in /etc/modprobe.d, named for example dell-smbios.conf, containing

blacklist dell_smbios

You might need to update your initramfs:

sudo update-initramfs -u
