Description Michelangelo De Simone 2016-11-14 23:16:11 UTC

Booting FreeBSD 11-RELEASE into a VMware Fusion virtual machine set to use the EFI firmware leads vt to be "very slow" while showing kernel messages.

Latecy returns within acceptable limits when the shell comes up.

To reproduce:

1. Create a new VM in VMware Fusion
2. Edit the .vmx file within the VM directory and add the line firmware = "EFI" somewhere.
3. Boot from the amd64 ISO disc1.

To be clear: BIOS is the default for a new VMware Fusion VM for a FreeBSD host.

Can you test with -current after 310177 (EARLY_AP_STARTUP on by default) and see if this is still reproducible?
