https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=194641 Bug ID: 194641 Summary: [EFI] boot/loader.efi: miscompilation on Intel Haswell with AVX2 Product: Base System Version: 11.0-CURRENT Hardware: amd64 OS: Any Status: Needs Triage Severity: Affects Some People Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: ohartman@zedat.fu-berlin.de Compileing world on Intel Haswell with CPUTYPE?=native set in either /etc/make.conf and/or /etc/src.conf renders /boot/loader.efi to fail: the EFI boot process stops and freezes when loader.efi is loaded. The problem affects only Haswell-based hardware (from my point of view, it seems to be AVX2), since Sandy_bridge and Ivy-Bridge based systems do not show the problem, even if world/kernel is compiled with -O3 and -march=native as I have tested on several CURRENT systems with most recent CURRENT as of today (FreeBSD 11.0-CURRENT #2 r273743: Mon Oct 27 19:51:01 CET 2014 amd64). The problem has been discussed recently on the CURRENT mailing list, but no PR has been issued so far. Please look at http://freebsd.1045724.n5.nabble.com/CURRENT-EFI-boot-failure-td5949387.html oh -- You are receiving this mail because: You are the assignee for the bug.
