Linux Decides To Disable RNG On All AMD fTPMs

For those out of the loop, some AMD users have been suffering from stuttering issues caused by the AMD fTPM random number generator. A firmware/BIOS update appears to fix the issue for some users, but not others, leading to more bug reports being sent in. Last week, Linus Torvalds said “let’s just disable the stupid fTPM hwrnd thing”, and, as of today the Linux kernel has gone ahead and blanket disabled RNG use for all current AMD fTPMs.

    I assume there’s a kernel boot param that allows for disabling it if you get affected in a kernel older than the one they’ll be disabling this.
