A few more things: /proc/cpuinfo reports both `sme` and `sev`. cpuid confirms that the relevant cpu register bits are set: $ cpuid -r -1 -l 0x8000001f CPU: 0x8000001f 0x00: eax=0x0001000f ebx=0x0000016f ecx=0x000001fd edx=0x00000001
$ modprobe msr $ rdmsr 0xC0010010 f40000 $ grep CONFIG_AMD_MEM_ENCRYPT /boot/config-5.4.0-29-generic CONFIG_AMD_MEM_ENCRYPT=y # CONFIG_AMD_MEM_ENCRYPT_ACTIVE_BY_DEFAULT is not set I tried finding additional options with regards to SME in the uefi, but there were none. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1879538 Title: System freeze when booting with mem_encrypt=on To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1879538/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
