intel rng bypass fwh detection
Could you test this patch and insert the intel-rng module with no_fwh_detect=1
It should continue even when it finds BIOS locked
hi, sorry for the delay. it works dmesg says: intel_rng: no version for "struct_module" found: kernel tainted. Intel 82802 RNG detected and rngd is starting and producing random numbers regards Vassilios Fedora apologizes that these issues have not been resolved yet.
