Hi, Our server is getting stuck on updating packages. We can not seem to get past the upgrade to glibc. Sometimes it fails, with an error, and sometimes it actually kills the machine requiring reboot, examples of both below. Sorry if this is a known problem, but I've been looking and struggling with it for a couple of weeks. Any help would be appreciated, here's the info from emerge, emerge --info Gentoo Base System version 1.6.14 Portage 2.0.54 (default-linux/x86/2006.0, gcc-3.4.4, glibc-2.3.5-r1, 2.6.7-gentoo-r14 x86_64) ================================================================= System uname: 2.6.7-gentoo-r14 x86_64 AMD Opteron(tm) Processor 250 dev-lang/python: 2.3.5-r2, 2.4.2 sys-apps/sandbox: 1.2.12 sys-devel/autoconf: 2.13, 2.59-r6 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r1 sys-devel/binutils: 2.16.1 sys-devel/libtool: 1.5.22 virtual/os-headers: 2.6.11-r2 ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-mtune=opteron -march=opteron -O3 -funroll-loops -fomit-frame-pointer -fprefetch-loop-arrays -pipe -ftracer -mmmx -msse -msse2 -m3dnow -mfpmath=sse" CHOST="x86_64-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/2/share/config /usr/kde/3/share/config /usr/lib/X11/xkb /usr/lib64/mozilla/defaults/pref /usr/share/config /usr/share/texmf/dvipdfm/config/ /usr/share/texmf/dvips/config/ /usr/share/texmf/tex/generic/config/ /usr/share/texmf/tex/platex/config/ /usr/share/texmf/xdvi/ /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/terminfo /etc/env.d" CXXFLAGS="-mtune=opteron -march=opteron -O3 -funroll-loops -fomit-frame-pointer -fprefetch-loop-arrays -pipe -ftracer -mmmx -msse -msse2 -m3dnow -mfpmath=sse" DISTDIR="/usr/portage/distfiles" FEATURES="autoconfig distlocks sandbox sfperms strict" GENTOO_MIRRORS="http://distfiles.gentoo.org http://distro.ibiblio.org/pub/linux/distributions/gentoo" MAKEOPTS="-j4" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="x86 3dnow X acpi alsa apache2 audiofile avi bitmap-fonts bzip2 crypt cups dga eds emboss encode exif expat fam fbcon foomaticdb fortran gd gdbm gif glut gpm gstreamer gtk gtk2 imagemagick imlib ipv6 java jikes jpeg junit lcms libg++ libwww mad mailwrapper mhash mikmod mmx mng mozilla mp3 mpeg mysql ncurses nptl ogg oggvorbis opengl pam pcre pdflib png python quicktime readline samba sdl slang spell sse ssl tcpd tetex tiff truetype truetype-fonts type1-fonts udev userlocales vorbis xml xml2 xmms xv zlib userland_GNU kernel_linux elibc_glibc" Unset: ASFLAGS, CTARGET, LANG, LC_ALL, LDFLAGS, LINGUAS The error from dying machine is, CPU 0: Machine check Exception 4 Bank 0: f60c200000000136 TSC 177daa0cc8aof ADDR 1af80e80 Kernal panic: Machine check The error msg from (non-dying) Emerge -av sys-lib/glic x86_64-pc-linux-gnu-gcc iso_2033.c -c -std=gnu99 -O2 -Wall -Winline -Wstrict-prototypes -Wwrite-strings -march=opteron -mtune=opteron -pipe -fPIC -I../include -I. -I/var/tmp/portage/glibc-2.3.5-r2/work/build-default-x86_64-pc-linux-gnu-lin uxthreads/iconvdata -I.. -I../libio -I/var/tmp/portage/glibc-2.3.5-r2/work/build-default-x86_64-pc-linux-gnu-lin uxthreads -I../sysdeps/x86_64/elf -I../linuxthreads/sysdeps/unix/sysv/linux/x86_64 -I../linuxthreads/sysdeps/unix/sysv/linux -I../linuxthreads/sysdeps/pthread -I../sysdeps/pthread -I../linuxthreads/sysdeps/unix/sysv -I../linuxthreads/sysdeps/unix -I../linuxthreads/sysdeps/x86_64 -I../libidn/sysdeps/unix -I../sysdeps/unix/sysv/linux/x86_64 -I../sysdeps/unix/sysv/linux/wordsize-64 -I../sysdeps/unix/sysv/linux -I../sysdeps/gnu -I../sysdeps/unix/common -I../sysdeps/unix/mman -I../sysdeps/unix/inet -I../sysdeps/unix/sysv -I../sysdeps/unix/x86_64 -I../sysdeps/unix -I../sysdeps/posix -I../sysdeps/x86_64/fpu -I../sysdeps/x86_64 -I../sysdeps/wordsize-64 -I../sysdeps/ieee754/ldbl-96 -I../sysdeps/ieee754/dbl-64 -I../sysdeps/ieee754/flt-32 -I../sysdeps/ieee754 -I../sysdeps/generic/elf -I../sysdeps/generic -nostdinc -isystem /usr/lib/gcc/x86_64-pc-linux-gnu/3.4.4/include -isystem /usr/include -D_LIBC_REENTRANT -include ../include/libc-symbols.h -DPIC -DSHARED -DNOT_IN_libc -o /var/tmp/portage/glibc-2.3.5-r2/work/build-default-x86_64-pc-linux-gnu-linux threads/iconvdata/iso_2033.os -MD -MP -MF /var/tmp/portage/glibc-2.3.5-r2/work/build-default-x86_64-pc-linux-gnu-linux threads/iconvdata/iso_2033.os.dt -MT /var/tmp/portage/glibc-2.3.5-r2/work/build-default-x86_64-pc-linux-gnu-linux threads/iconvdata/iso_2033.os ../iconv/skeleton.c: In function `gconv_init': ../iconv/skeleton.c:350: internal compiler error: in expand_stmt, at c-semantics.c:883 Please submit a full bug report, with preprocessed source if appropriate.
