During resume from hibernation, I started to see the warning below since

drm/i915: Add messages useful for HPD storm detection debugging (v2)
the system is otherwise working properly, and so far it seems to happen
only during hibernation resume.

If this really needs to be enabled unconditionally by default (?), having
it to warn only once would be nice.
If there is anything else I could do to make this go away, please let me

This is a standard x200s thinkpad, no fancy development HW.

Can you please attach full dmesg from boot up to the first WARN with
drm.debug=0xe? This really shouldn't happen and indicates a bug
somewhere ...
Cheers, Daniel

A bit difficult ... I originally thought that it was reliably
reproducible, but now I didn't get it after 10 suspend/resume cycles. Will
keep following it, and once it appears, will send you the dmesg.

OK, I haven't been able to reproduce this any more for ~week ... so please
disregard this, and I'll report back if it comes back (will be running
with full drm debug output for some time).

Hi Jiri,
Just found your email, it got missed do to a temporary inaccessibility to
my email.

Could you check if you get any messages regarding HPD storms after
suspend/resume ie messages like:
"[drm] HPD interrupt storm detected on connector HDMI-A-1"
but without the annouing warn messages?
I cannot find anything obviously wrong in the code.
However there are several code paths for different hardware though - could
you give me an 'lspci -n' output so I can narrow them down?
Thanks!
Cheers,
Egbert.

I have this:
[357128.184113] [drm] HPD interrupt storm detected on connector DP-3: switching from hotplug detection to polling
It appeared in the log approximately 5 seconds after resume has been
completed.
Thanks,

Okay, and it just happened during resume from RAM (it was a very long
series of repeating the same trace, I am putting here just the last
portion):
