Same problem here, E3-1230 v5. Stretch guest VM on RHEL 6.6 host. Actually on my guest VM, this bug was from *4.8-rc8*, while 4.8-rc7 boots well.
I do not have access to the host machine, so cannot test if those changes in configuration works or not. cpuinfo: processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 94 model name : Intel(R) Xeon(R) CPU E3-1230 v5 @ 3.40GHz stepping : 3 microcode : 0x1 cpu MHz : 3407.998 cache size : 4096 KB physical id : 0 siblings : 1 core id : 0 cpu cores : 1 apicid : 0 initial apicid : 0 fpu : yes fpu_exception : yes cpuid level : 13 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ss syscall nx pdpe1gb lm constant_tsc arch_perfmon nopl eagerfpu pni pclmulqdq ssse3 fma cx16 pcid sse4_1 sse4_2 x2apic movbe popcnt tsc_deadline_timer aes xsave avx f16c rdrand hypervisor lahf_lm abm 3dnowprefetch xsaveopt fsgsbase bmi1 hle avx2 smep bmi2 invpcid rtm rdseed adx bogomips : 6815.99 clflush size : 64 cache_alignment : 64 address sizes : 39 bits physical, 48 bits virtual power management:
