https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=200274 Bug ID: 200274 Summary: buildworld bus error MachineLICM.o for i386 targets 10.1S r283021 Product: Base System Version: 10.1-STABLE Hardware: i386 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: dewayne@heuristicsystems.com.au Bus error from MachineLICM.o arises during buildworld of i386 pentium3 systems on (uname -aKU) FreeBSD hathor 10.1-STABLE FreeBSD 10.1-STABLE #0 r282448M: Wed May 6 02:20:33 AEST 2015 root@hathor:/usr/obj/prod/100102/D/K8/usr/src/sys/hqdev-amd64-smp-vga amd64 1001514 1001514 from svnlite, Last Changed Rev: 283021 I perform a build sequence which includes using CPUTYPE's c3-2, pentium3, prescott (plus a few amd64 worlds). During the last three cycles (about 2 weeks apart) only ONE of the i386 build worlds will fail (none fail for amd64 targets) They use a common set of scripts where MAKEOBJPREFIX, CPUTYPE, TARGET_CPUTYPE and -march= or -mtune= variables are changed. Aside typically each has 4 kernels, also all of these build without error. The following is taken from the pentium3 failure which occurred last night. Yesterday if failed for the c3-2 build. Very puzzling. Hardware: Xeon E3-1230L, build disk SSD (Kingston SV300). smartctl reports overall health: Passed --- MachineLICM.o --- Stack dump: 0.
