log

I am observing the following kernel message on a Lenovo ThinkPad X9-14 Gen 1
running Arch Linux on an Intel CPU:

kvm_amd: CPU 1 isn't AMD or Hygon

# System information

Kernel: 6.19.6-arch1-1
Distribution: Arch Linux
Laptop model: Lenovo ThinkPad X9-14 Gen 1 (21QBS0KV00)
CPU: Intel Core Ultra 7 268V
Architecture: x86_64

# CPU information (lscpu)

Vendor ID: GenuineIntel
Model name: Intel(R) Core(TM) Ultra 7 268V
Virtualization: VT-x

# Loaded KVM modules

lsmod | grep kvm

kvm_intel 516096 1
kvm 1462272 3 kvm_intel
irqbypass 16384 1 kvm

# Observations

* The system uses an Intel CPU (GenuineIntel).
* The Intel KVM module (kvm_intel) loads normally.
* However, during boot the following message appears:

kvm_amd: CPU 1 isn't AMD or Hygon

* The system does not have an AMD CPU.
* It appears the kvm_amd module may be probed or initialized briefly
even on Intel systems.

# Attachments

The following are attached:

* sudo dmesg
* lscpu
* lsmod
* sudo acpidump
