My Elitbook can't boot the USB memstick 10.1-RC2: "BTX Halted" error message. This problem should be on the USB memstick image format, because this laptop can boot and run 10.1-RC1 (an old 10.0 upgraded) without problem from its hard drive.
The same here with HP EliteBook 2740p that can only boot from USB (no OpticalDrive). Load hangs at random times in bootloader and/or kernel load. I had to do a PXE Boot Install to get system running. In other situation I have noticed USB HUB problems. My USB Ethernet adapter does not work here when connected directly to a port, but works when connected via USB HUB. Maybe that would be a hint :-)
Updated 10.1-BETA and 10.1-RC versioned bugs to 10.1-STABLE.
I did a re-try with: - FreeBSD-11.0-CURRENT-amd64-r283577-20150526-memstick.img - FreeBSD-10.1-STABLE-amd64-20150601-r283892-memstick.img - FreeBSD-10.1-STABLE-amd64-20150601-r283892-uefi-memstick.img => Same problem: BTX loader 1.00 BTX version is 1.02 Consoles: internal video/keyboard BIOS drive C: is disk0 BIOS drive D: is disk1 BIOS drive E: is disk2 BIOS 635kB/3086068kB available memory FreeBSD/x86 bootsrap loader, Revision 1.1 (root@releng1.nyi.freebsd.org, Mon Jun 1 21:08:16 UTC 2015) - int=0000000d err=00000038 efl=00010046 eip=00009094 eax=00000013 ebx=00002820 ecx=00000038 edx=000008ee esi=00009601 edi=00005f98 ebp=00080001 esp=00000000 cs=0008 ds=0000 es=0000 fs=0000 gs=0000 ss=0010 cs:eip=0f 00 d9 ba 00 a0 00 00-36 0f b7 05 13 04 00 00 c1 e0 0a 2d 00 10 00 00-29 d0 b1 33 51 50 68 02 ss:esp=f1 2e 00 f0 f1 2e 00 f0-c3 e2 00 f0 f1 2e 00 f0 f1 2e 00 f0 54 ff 00 f0-c3 f0 00 f0 f1 2e 00 f0 BTX halted Notice that my laptop had 8GB of RAM… and the available memory reported here is 3086068kB (=3GB).
I've just reach to boot my HP EliteBook a 12-current r306668 from an USB memstick (in UEFI mode).
Olivier tells me that it's fixed and this bug can be closed.
Awsome! Thank you! I have seen huge progress especially in UEFI boot in FreeBSD 12.0 RELEASE. Thank You! :-)
