Dear Maintainer,
noht has no effect.
I have been trying to chase down a weird hang which occurs only on 6
core/12 thread Ryzens (I cannot reproduce it on 4/8 or older CPUs).
As a part of that I tried to disable ht. Well, it cannot be disabled
- the noht command line arg has no effect whatosever.
As ht can be a security hole this may have security implications as
well.
Do you mean 'nosmt'? (See kernel-parameters.txt).
You can find further information as well in
