Created attachment 147333 [details] picture of problem I wrote the EFI Mememory stick image for 10.1 Beta 1 to a memory stick, which hangs right after loading the kernel.
Please add specific hardware details to this PR; this issue has been observed before, but is hardware- (or UEFI firmare-) specific.
ASUS P8B75-M/CSM w/ intel i5-3330. Do you need any other hardware details?
It'd be great if you can add the firmware version info too. I see from the specs that there's a serial port on an internal header. Is it possible for you to connect to this from another computer and switch to the serial port to test way? From the keyboard you'd break to the loader prompt and excute: OK set console=comconsole then over the serial console OK boot -v which should provide more insight into where things fail.
It says version 2.10.1208. Sorry, I have nothing else to connect a serial cable to.
Same behavior on RC2.
Just a through???? Bug 194793 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=194793 The above bug is also reported to fail on an asus system with American Megatrends firmware and the same EFI version: 2.31
Updated 10.1-BETA and 10.1-RC versioned bugs to 10.1-STABLE.

I have the same problem with Asus J1900I-C: http://www.asus.com/Motherboards/J1900IC/ Please check my output in attached files: Asus J1900I-C UEFI Bootloader VGA.jpg - VGA output of UEFI Bootloader Asus J1900I-C UEFI Bootloader Comconsole.txt - text output from serial console To get serial console output I needed to disable CSM (Compatibility Support Module) in the UEFI configuration. Disabling CMS causes that is impossible to boot legacy OS. With CSM enabled and booting with UEFI mode I got the only: Start @ 0xffffffff802db5c0 ... / The motherboard has the newest firmware version: J1900I-C BIOS 0610 Boot image: FreeBSD-10.1-RELEASE-amd64-uefi-memstick.img
Adding re@ to CC, although I think it is unlikely this will be resolved before 10.2-RELEASE (I have the same problem on my laptop...).
If possible can you please test the patch (or prebuilt image) in 191564?
This is believed to be fixed for everybody in FreeBSD -current as of today (revision 286667). Please test at your earliest convenience.
