Re: Applying kernel patch 118844-28 kills Nvidia module
Happened to me early last month when installing 118844-27.
I too installed the latest drivers, with no success.
Resolution was found in the NVidia drivers/sx86/video/readme.txt file located on the supplemental cd that shipped with the Ultra 20.
The configuration reboot after the kernel patch assigned the board to the next device instance. This is not the exact error reported in the readme, but the effect was the same.
This bug is not fixed (per readme) but workaround was to remove the "nvidia" entries from /etc/path_to_inst then performing a configuration reboot.
X came up fine after reboot.
