(Caused Black Screen, and reboot. Found this in the crashed kernel logs on /var/crash) Works fine on vmlinuz-4.18.0-372.26.1.el8_6.x86_64 and vmlinuz-4.18.0-372.16.1.el8_6.x86_64

The workstations with E5-2609, E5-2650 or E5-2630 are not affected - all of them run qemu-kvm VM under kernel-3.10.0-1160.80.1.el7.x86_64 without problems.

Thankfully, no problems with 2x Xeon E5-2667 v2 and CentOS 7.9 kernel 3.10.0-1160.80.1.el7.x86_64.
