I should also note that both systems (the working and the failing) are Xen DomU configurations. The output of /proc/cpuinfo for 1 CPU: # cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 42 model name : Intel(R) Core(TM) i5-2500K CPU @ 3.30GHz stepping : 7 cpu MHz : 3309.776 cache size : 6144 KB fpu : yes fpu_exception : yes cpuid level : 13 wp : yes flags : fpu de tsc msr pae cx8 cmov pat clflush mmx fxsr sse sse2 ss ht syscall nx lm up rep_good aperfmperf unfair_spinlock pni pclmulqdq ssse3 cx16 sse4_1 sse4_2 popcnt aes hypervisor lahf_lm ida arat epb pln pts dts bogomips : 6619.55 clflush size : 64 cache_alignment : 64 address sizes : 36 bits physical, 48 bits virtual power management: As further confirmation of my suspicions, I downloaded the test case program attached to #720126 and got the same output: # ./exe Hello, World! Illegal instruction Added link to same bug on bugs.debian.org with attached patch.
