Is there any way this can get pushed to precise instead of precise- updates? See https://bugs.launchpad.net/ubuntu/+bug/1007439 - it's now impossible to use xen-tools (e.g. xen-create-image) to make a 12.04 guest because this bug is hit almost instantly during the debootstrap install process (which doesn't comprehend -updates). Although that bug is related to installing a precise guest under XenServer, you can observe this behavior by trying to install a precise guest on a precise domU with a CPU that is affected by this bug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/956051 Title: libc6 crash while running 'xm' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/eglibc/+bug/956051/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi It appears this issue can be worked around by adding the following options to xen's command line in grub. cpuid_mask_ext_ecx=0xFFFEFFF cpuid_mask_ecx=0xEFF This masks both FMA4 and AVX from cpuid for dom0 and all domU's Also note that xen has a cpuid option for domU configs that allows to you mask these as well, but it doesn't seem to work for userspace making direct cpuid calls. The kernel will see that fma4 isn't there, but glibc still see's it as available and you get crashes. jim -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/956051 Title: libc6 crash while running 'xm' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/eglibc/+bug/956051/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi Some additional information that leads me to believe this is a xen issue. gcc 4.6.3 code has the following #define OPTION_MASK_ISA_FMA4_SET \ (OPTION_MASK_ISA_FMA4 | OPTION_MASK_ISA_SSE4A_SET \ | OPTION_MASK_ISA_AVX_SET) So when you use -mfma4 option it also enables avx instruction set.
