Using Dell DKMS Drivers After Upgrading the Kernel
If the kernel is upgraded in a system where the DKMS driver is installed, then
after the kernel upgrade perform the following procedure to ensure that the
updated DKMS driver is installed for the latest kernel.
• If the module version of the updated kernel is higher than the dkms driver
version, then continue using the native driver.
• If the module version in the updated kernel is lesser than the DKMS driver
version, then use the DKMS driver. Create a file in
/etc/depmod.d with the
filename dkms_module_name.conf with an entry as below:
override module_name kernel_version
modules_directory
For example, for the bnx2 driver, create a file bnx2.conf in /etc/depmod.d/
with the below contents:
override bnx2 2.6.18-x.el5 weak-updates
Run the depmod -a command
For more information on DKMS, see the DKMS main page on your system.
