Description Ilya Zhuravel 2010-01-18 17:20:02 UTC 
When trying to install freeBSD 8.0 on ESX server 3.5 after selecting any loader option i get an error BTX halted.

I also get some kind of memory dump.
Could it be connected to bios settings or is it my virtual machine or even HW (Intel XEON 64 bit). 

Please he-e-e-e-elp.

Sincerely yours,
Ilya Zhuravel

Fix: 

Googled alot but haven't found any specific answer why this happens.
How-To-Repeat: Install an installation DVD and press 1. If you see "BTX halted" exception you've got the same problem.

There's been a lot of changes to btx since this, and they have likely fixed this bug. ESX server 3.5 is also kinda hard to come by these days. This boot path works in many other VM systems with newer FreeBSD versions. If you can still reproduce this problem with FreeBSD 11 or 12 images, please file a new bug, and cc me so we can get to the bottom of it.
