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 4 '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. – user373503 Oct 18 '19 at 6:54

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
