Comment # 14 on bug 1185542 from Paul Graff

Does not appear to work the following message is displayed.

[     0.486287] x86/cpu: VMX (outside TXT) disabled by BIOS
[80.597573] watchdog: BUG soft lockup - CPU#0 stuck for 23s! [kworker/u44:0:8]
then very fast scrolling lines and halt as same as before -- 
[  155.213574] Kernel Offset: disabled

System then automatically reboots after a certain period of time.

I will double check adding kfence.sample_interval=0 to kernel parameter again
but quite certain no joy.
