--- Comment #1 from Bryn M. Reeves <bmr at redhat dot com> ---
This is expected when passing -1 as the delay interval: I originally wrote the
tapset to allow controlled simulation of driver bugs that triggered
softlockups.

The guru-delay tapset is useful for introducing (normally short) controlled
delays at specified probe points; if the specified delay interval exceeds the
configured softlockup threshold for the system it will trigger these warnings.

This is the reason the tapset is named 'guru-delay' and requires -g to be used
- Frank suggested this name and restriction during review to prevent an
unprivileged user impacting other system activities.
