 after update

Hello,

the bug was first reported on VMware Workstation by rdkehn.

On my setup (archlinux text mode only VM on ESXi 8.0U3 latest) the kernel does NOT crash, the screen just goes dark after switching the console from

[    2.745694] Console: switching to colour dummy device 80x25

to

[    2.771998] Console: switching to colour frame buffer device 160x50

You see the VMware remote console resizing, then going black and from this point no more output.

I have attached boot_journal and vmware.log from my setup. VM uses EFI boot and SVGA with defaults as display adapter, I attached the vmx file too.

Best,
-ap
