[Bug 956051] Re: libc6 crash while running 'xm'

[Tom Worley]

Unfortunately this is still affecting me, and I can't get Ubuntu 12.04 LTS server installed on fully patched XenServer 6.0.2
I tried to get around it by installing Ubuntu 10.04.4 LTS and upgrading to 10.10->11.04->11.10 (all fine) and then the upgrade from 11.10->12.04 failed with the Python upgrade crashing aborting the install with more than half of the packages not upgraded, and keeps crashing each time I try to apt-get dist-upgrade:

Setting up python2.7-minimal (2.7.3-0ubuntu3) ...
Illegal instruction (core dumped)
dpkg: error processing python2.7-minimal (--configure):
 subprocess installed post-installation script returned error exit status 132
Errors were encountered while processing:
 python2.7-minimal

syslog shows:

Title:
  libc6 crash while running 'xm'

Status in “eglibc” package in Ubuntu:
  Confirmed
Status in “eglibc” source package in Precise:
  Confirmed

Bug description:
  Ubuntu Version: 12.04 (precise)

  libc6: 2.15-0ubuntu5
  xen-hypervisor-4.1-amd64: 4.1.2-2ubuntu2
  linux-image-generic: 3.2.0.18.20

  Everytime I try to run 'xm list' on a new AMD Opteron 6274 system (Bulldozer architecture) I'm getting a crash.
  I couldn't even file a bug report through "apport-bug".
  Repeating the same procedure with Ubuntu Oneiric showed no problems at all.

  dmesg showed following messages:
