https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D270534 Chuck Coffing <ccoffing@gmail.com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |ccoffing@gmail.com --- Comment #4 from Chuck Coffing <ccoffing@gmail.com> --- I just encountered this same "BTX halted" with the same cs:eip instruction stream, on an AMD K6-III booting FreeBSD 13.2 i386 bootonly iso. The documentation at https://www.freebsd.org/platforms/i386/ claims that the i386 port will run on any i486 and newer. However, notice the instruction stream: cs:eip=3D0f 45 0f 45 is CMOVNE. The CMOV instructions were introduced with the Pentium Pr= o.=20 The original reporter's P5 90 and my K6-III are both i586-class and do not support these i686 instructions. I would expect that the BTX should be built using conservative instruction = set, and more sophisticated CPU identification is done later in the boot. So my guess is that BTX is being built wrong (for example, maybe no "-mtune"). --=20 You are receiving this mail because: You are the assignee for the bug.=
