For anyone monitoring this thread, this issue has been determined to be a unknown CPU issue (Lenovo X250 i7) I'll provide updates once new Laptop arrives! Cheers Jeremy for the help!

Oh I think I messed up before and disabled the other cores, sorry this is my actual cpuinfo: ➜ ~ cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 61 model name : Intel(R) Core(TM) i7-5600U CPU @ 2.60GHz stepping : 4 microcode : 0x25 cpu MHz : 2593.962 cache size : 4096 KB physical id : 0 siblings : 4 core id : 0 cpu cores : 2 apicid : 0 initial apicid : 0 fpu : yes fpu_exception : yes cpuid level : 20 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr...

Ah awesome, I've actually tried 1.4Mhz, it works, its discoverable on UEs, however I can't attach and on top of that I still get thoes errors above spammed?

Cheers Jeremy! I actually got hit with 5 gaps during this test: ➜ ~ ./blade_gaps.py /dev/shm/samples_15.36msps.check [16106127] = 0, Expected 16106127, Gap = 16106127 [32212254] = 0, Expected 16106127, Gap = 16106127 [48318381] = 0, Expected 16106127, Gap = 16106127 [64424508] = 0, Expected 16106127, Gap = 16106127 [80530635] = 0, Expected 16106127, Gap = 16106127 Number of gaps:5 Does this mean CPU or USB Bus? Awesome! Squashing Bugs!

Thanks heaps for this info! So I successfully disabled hyperthreading, the OS only sees one core running at its max freq, I've also run the 'gap' test on the USB Bus as per the link above and it came back 'No Gaps', was there more I had to test for the USB Bus? 00:1d.0 USB controller: Intel Corporation Wildcat Point-LP USB EHCI Controller (rev 03) (prog-if 20 [EHCI]) Subsystem: Lenovo Wildcat Point-LP USB EHCI Controller Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping-...
