Hi. On a laptop with Intel HD Graphics 5500, after waking up from sleep mode, I got some error messages (the system continues to work after that):
Feb 23 16:43:29 freebsd kernel: [drm ERROR :fw_domain_wait_ack_clear] render: timed out waiting for forcewake ack to clear.
Feb 23 16:43:29 freebsd kernel: drmn1: Failed to idle engines, declaring wedged!
Also, I attach all /var/log/messages for today's date.
After that, the graphics is drawn very slowly. This is especially noticeable when dragging windows or viewing web pages through the browser.
Today the error appeared again, on FreeBSD 13.0-BETA 4. In /var/log/messages, everything is the same.
can you post any sysctls, loader.conf tunables that might be related? and for history, which pkg versions are installed?
Hi, David. The pkg version I have is 1.16.3.
Contents of /boot/loader.conf related to the i915 driver:
$ sysctl compat.linuxkpi
Hi, a while ago I reported (I believe) the same problem as yours here: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=253801
In my case, since 13.0-RC1 and now RC2, the issue has become harder to reproduce. What about you? Is it too less likely to happen now?

Hi, Patricio. Yes, it's the same problem. In 13.0-RC1, this occurred twice, before that, it happened more often. Now, in 13.0-RC2, I have not encountered this yet (updated yesterday).

Cool! That means it wasn't just my impression or a coincidence. So far it haven't happened here on 13.0-RC2 either.
How's it going for you lately?
Sadly, in my case it's gone completely backwards. Resuming from suspend is really broken right now on both 13.0-RC4 and 13.0-RC5. It's a real shame, and I'm afraid it's gonna make it to 13.0-RELEASE :(

Hmm. I have been doing some updates around the house. This laptop (a Dell Latitude E5430) is on RC4 and it suspends ok. I have the following set, if it matters:
I will check the other laptop, which is on RC5, later.
So, this is puzzling.

Thanks for replying!
I think this problem is very hardware-specific after all, as I have Intel HD Graphics 5500 just like Igor Osminin (who first reported the issue).
And I have "hw.acpi.lid_switch_state=S3" too, but don't think it's related to this bug really.
Hi everyone, I think I finally made some progress to workaround this issue. I explained it on the other bug report about this problem:
