Unfortunately, it doesn't seem to be rock stable on AMD hosts :( When
using Nehalem on my AMD Ryzen Threadripper 2920X, I get hangs during
installation of Debian 11 and for an already existing one, crashes
during boot. This is with or without AES flag. Colleagues with AMD CPUs
also ran into similar issues when using CPU type Nehalem.
Note that these were not server CPUs, Aaron said, he'll test those later
(please reply to here with the results :)).
It would be bad if too many AMD CPUs aren't happy with the new default
:/ In the worst case, we'd only be able to switch to the new default for
Intel hosts.
What AMD CPUs did you try it on?
