Re: Failed to check for processor microcode upgrades(x86_64)

funnily was about to post a similar topic than "destroyer"

have encountered this both on amd and intel computer, the software says

spec_store_bypass: Mitigation of SSB disabled via prctl

thought this might have caused myself since i had "secure boot" or similar in place, but disabled afterwards for some reason currently unknown.

here is the output for the intel computer; for amd it is similar;
