[Bug 956051] [NEW] libc6 crash while running 'xm'

[Adrian Stachowski]

Public bug reported:

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:

[  479.891581] xm[1746] trap invalid opcode ip:7fd684f8a5fc sp:7fff3ebb3c70 error:0 in libm-2.15.so[7fd684f48000+f9000]
