Bug 210849

Kernel 5.7.0 works fine

More bugs like this https://bugzilla.redhat.com/show_bug.cgi?id=1881889

5.10.1 builded from sources have same result

Have new error messages linkied with it, i think
drm failed to load unicode id
amdgpu: RAP: optional rap ta ucode is not available
kernel 5.10.2

There is an old bug report that has been closed related to /usr/lib/firmware/amdgpu/raven_dmcu.bin.  This file was being incorrectly loaded or has a probelm. To correct this, I renamed the file to raven_dmcu.bin.old so that it would not load.  The problem would return every time firmware updates would come through that supplied a new raven_dmcu.bin.

I had no problems until recently when the kernel was bumped from 5.8.18-200.fc32.x86_64 to the first instance of 5.9.

The previous fix was accomplished y uninstalling the kernel, rename the troublesome file, and then reintall the kernel.

I took another look today and see there is a new raven_dmcu.bin so I will repeat the procedure again.  It may not be the same problem, but I will give it a try.

I tried the fix in Comment 5 and it does not work so I am sticking with the 5.8.18 kernel until this gets ironed out.

In the 5.18 kernel which does not hang on me I also have a segfault:

This happens coming out of suspend. So pretty sure amdgpu is the culprit.

'no_console_suspend' in boot options fix problem absolutely in my case. maybe this is temporally fix, but i hope it will be fixed normally.

This bug has basically disabled two different machines I have that use AMD graphics cards.  One, a work station running Fedora 33 will lose the display if I do not log on right away after a power up.  The defaults that blank the screen or just a simple lock screen sequence basically causes the monitor to shutoff to save energy. At this point the display can not be recovered since the driver loses it self.  It is a real shame as this system was working perfectly for over a year beofre this happened.  The guilty patch should be reverted immediately.

I can remote into the system from elsewhere ussing ssh and command a reboot to bring it back.  The kernel underlying is running and completely functional. The device driver AMDGPU is 'F'ed up.  In my many many years of using Fedora and other linux distros, this is by far the worse cluster bug I have ever see.

Can you bisect?

I have done some bisection with the kernel by uninstalling packages and rolling back. I tried this with my best guess of which packages to roll back using package manager (dnf here).  In the recent past I have seen issues with the amdgpu firmware and was able to disable the bug by hiding the suspect file removing the kernel and reinstalling the kernel.  This was needed because the firmware is folded into the boot image when the kernel is installed.

I was not successful with this bug here yet.

Firmware vs mesa/dri code? If someone could point me to the correct source repository, I would be happy to attempt a raw build and install to see if latest development branches have fixed and then if not I could try starting a bisection on it.

most likely kernel.

OK, I have done the kernel builds before no problems.  I will start back about a year and go from there.

Dropped back to kernel-5.7.0 and everything works fine on laptop with lid close suspend / returns from suspend with no errors on my laptop.  I made no other changes so this confirms the kernel is the focus.

No noy fixed.  I ahve tried up to:

5.11.3-50.fc33.x86_64"

Exact same failure.  I have add to clear off a buncg of files to make room on this laptop to start doing kernel builds in hopes of identifying the breakage.
