https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=217512 Bug ID: 217512 Summary: boot2 is unable to load kernel directly Product: Base System Version: 11.0-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Many People Priority: --- Component: misc Assignee: freebsd-bugs@FreeBSD.org Reporter: mark@uncommon.com Loading a kernel directly using boot2 causes the invalid-opcode fault like the following: int=00000006 err=00000000 efl=00010046 eip=c0300000 eax=002ff000 ebx=000213d0 ecx=00000000 edx=a030ff1e esi=00018504 edi=0008eb78 ebp=0008ebc8 esp=0000940b cs=0008 ds=0010 es=0010 fs=0010 gs=0010 ss=0010 cs:eip=ff ff ff ff ff ff ff ff-7f 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00-00 00 00 00 00 00 00 00 ss:esp=36 80 0d 07 90 00 00 01-e9 ba fc ff ff aa ac 84 c0 0f 84 86 00 00 00 a8-80 74 f2 88 c5 b0 3d aa BTX halted This is using a GENERIC unmodified amd64 kernel (installed from HD from DVD iso source (11p1) and trying /boot/kernel/kernel at boot: prompt. SAS/SATA drive environment. Tested both MBR and GPTBOOT versions of boot2 (/boot/boot and /boot/gptboot)-no joy. /boot/loader works with no problem as well as just press [return] at the prompt. We need this feature to be working in our secure server environments (bypassing the loader and directly booting a highly customized, self contained kernel). RE: boot(8) man page, 'it is possible to dispense with the third stage altogether'. However, hitting a key and specifying '/boot/kernel/kernel' results in hard stop (impossible to reboot with crtl-alt-del) after BTX halted message--requires power cycle. Booting '/boot/loader' works ok. Thanks in advance. -Mark -- You are receiving this mail because: You are the assignee for the bug.
