Enabling vt (newcons) and accidentally (and incorrectly?) having 915kms_load="YES" results in an endless reboot loop.
FreeBSD 11.0-CURRENT #4 r271499: Sat Sep 13 13:28:58 CEST 2014
Intel G45 chipset, Intel DG45ID motherboard
See also https://wiki.freebsd.org/Newcons - similar reports on other hardware, where i915kms_load="YES" produces a black screen and apparent hang. (This is how my ThinkPad X220 behaves.)
I have an USB disk with 11-CURRENT (r269739) and in /boot/loader.conf set:
while the disk boots fine on Acer EeePC 900 and Acer Aspire One D250,
it gives on Dell E6330 a black screen after some seconds of booting and
the system seems to hang; only power-cycle is possible; commenting-out
the i915kms_load line, the system boots up fine;
as it is reproduceable fine, I'm willing to help and insert debug messages
if someone could guide me through; thx
For what is worth, this does not happen with a S440 ThinkPad (Intel HD 4400 Haswell) with CURRENT 20150716-r285616.
I no longer have this hardware and it seems to work fine on newer releases
