https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=195160 Bug ID: 195160 Summary: ia64 cpu_halt() reboots system instead of halting Product: Base System Version: 10.1-RELEASE Hardware: ia64 OS: Any Status: Needs Triage Severity: Affects Some People Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: bruce.cran@gmail.com The cpu_halt() function is apparently supposed to stop the CPU, for example when a panic occurs - the x64 version is implemented via an infinite loop running the hlt instruction. On ia64 the implementation instead calls efi_reset_system() (http://fxr.watson.org/fxr/source/ia64/ia64/machdep.c?v=FREEBSD10;im=bigexcerpts#L402), which does a warm reboot and is probably not the expected behavior. -- You are receiving this mail because: You are the assignee for the bug.
