[Bug 1271534] Re: libc6-xen:i386 installation can cause panics on boot

[Launchpad Bug Tracker]

This bug was fixed in the package eglibc - 2.19-0ubuntu3

---------------
eglibc (2.19-0ubuntu3) trusty; urgency=medium

  * Merge with unreleased 2.19 from Debian experimental, fixing more bugs:
    - Fix bzero/__bzero definition on powerpc/ppc64 with static builds.
    - Enable IFUNC on arm64 builds, now that the toolchain supports it.
    - Revert removal of the XDR currency for installation-locale FTBFS.
    - Pull update from 2.19 branch, fixing bad math in __sin and __cos.
  * debian/sysdeps/{i386,amd64}.mk: Build i386 flavours with -fno-regmove,
    this can be reverted when gcc-4.9 becomes the default distro compiler.
  * debian/*: Drop the redundant libc6-xen packages on i386 (LP: #1271534)

Title:
  libc6-xen:i386 installation can cause panics on boot

Status in “eglibc” package in Ubuntu:
  Fix Released

Bug description:
  The eglibc package produces a special libc6 package for i386 Xen
  installations. This gets depended on by i386 Xen installs and causes
  (via some ld.config rule) binaries to dynamically link against those
  libraries. So while running inside a Xen guest (which dom0 is) the
  following is true:

  #> ldd /bin/sh
          linux-gate.so.1 =>  (0xb7734000)
          libc.so.6 => /lib/i386-linux-gnu/tls/i686/nosegneg/libc.so.6 (0xb757900)
          /lib/ld-linux.so.2 (0xb7735000)

  This creates a problem when update-initramfs is called inside dom0
  because the automatic library resolver will only pick up the special
  ones. When the host then gets rebooted into non-xen mode, this causes
  a panic on boot because the standard libraries are not included in the
  initramfs.
