            Bug ID: 104856
           Summary: `intel_hpd_cancel_work` takes around 1 s during
                    suspend on Dell XPS 13 9360
           Product: DRI
           Version: XOrg git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Intel
          Assignee: intel-gfx-bugs at lists.freedesktop.org
          Reporter: pmenzel+bugs.freedesktop at molgen.mpg.de

There seems to be a regression on the Dell XPS 13 9360, that during suspend the
method `intel_hpd_cancel_work` takes almost one second. `sleepgraph.py` [1] was
used to instrument this.

I’ll add the logs later.
