The reboot sequence before the change is:
(1) ACPI
(2) KEYBOARD
(3) ACPI
(4) KEYBOARD
(5) TRIPLE
The reboot sequence after the change is:
(1) ACPI
(2) KEYBOARD
(3) ACPI
(4) KEYBOARD
(ADD_1) EFI
(ADD_2) CF9
(ADD_3) BIOS
(5) TRIPLE
Steven's machine exactly hit (5), while CF9 hangs, so we encountered
this regression.
EFI is no question. So, Is everybody okay with the following sequence?
(1) ACPI
(2) KEYBOARD
(3) ACPI
(4) KEYBOARD
(ADD_1) EFI
(5) TRIPLE
(ADD_2) CF9
(ADD_3) BIOS
Thanks,
