I tried to use self encrypting disks (SED) and use the sedutil (
However I get an error message, that some kernel flag is not set correctly? What is the problem (there are others people who seem to to use sedutil successfully).

/sedutil/Release_x86_64# ./sedutil-cli --scan
Scanning for Opal compliant disks
The Kernel flag libata.allow_tpm is not set correctly
Please see the readme note about setting the libata.allow_tpm
