--- Comment #7 from bugzilla at colorremedies.com ---
I haven't been able to reproduce the intel_pipe_update_end error since the
original report. But I am able to fairly easily reproduce the kinject slowing
the whole system down to a crawl with any kernel version, with Firefox and an
external display. It happens no where near as easily without external display
connected.

Since the original report I've only been using normal Fedora kernels (without
extra debug options) and only stable versions of 4.17x. I'll retest soon with
4.18rc+debug kernels, and include the additional debug options you've
recommended.
