thanks for your reply..
Had issue with nvidia drivers latest. Read the Doc and found out that adding the module for nvidia would solve my issue.
Added module "MODULES="nvidia nvidia_modeset nvidia_uvm nvidia_drm". crc32ca was already there. Ran mkinitcpio -P and got the error. As far as issue, I have known. When running mkinitcpio I ignore warnings. This one is an error. Got me a bit stressed out. Tested a bit further: Couple of reboots and it seems, as of today, that I have no issue.
Posted to see if anyone had seen this, and to see if this is serious or not ! I could not find anything on the net.
