Subject: [Bug 217574] New: kvm_intel loads only after suspend

            Bug ID: 217574
           Summary: kvm_intel loads only after suspend
           Product: Virtualization
           Version: unspecified
          Hardware: Intel
                OS: Linux
            Status: NEW
          Severity: blocking
          Priority: P3
         Component: kvm
          Assignee: virtualization_kvm@kernel-bugs.osdl.org
          Reporter: drigoslkx@gmail.com
        Regression: No

Hi, I tested this bug on Slackware 5.15.29, 5.15.97 and 6.1
I tested too on ubuntu 23.04, Fedora 38 and Linux Mint 21.01 and got the same
results.

When I boot Linux, it shows the error
kvm: CPU 0 feature inconsistency!
(Depending on the kernel version it throws this message for each cpu core)

The kernel loads the kvm module but not kvm_intel.
(Without kvm_intel kvm doens't work).
If I try a manual load, doing modprobe kvm_intel it shows
modprobe: ERROR: could not insert 'kvm_intel': Input/output error

So I take some time break, when I back, the system was suspended, I turned it
on again, and tried to load modprobe kvm_intel, it works, and kvm got working
now.

Tested this in all other distros described above and got the same results.
I only get kvm works after a suspend.

My specs
Motherboard Jingsha x99
CPU Intel(R) Xeon(R) CPU E5-2696 v3 @ 2.30GHz
