Comment 1 looks like a new issue in DC. Looks like this might be related to the core DRM code now only initializing fbdev compatibility when a display connection is detected, like the change above. Sverd, until the latter is fixed, maybe you can try if amdgpu.dc=0 helps. Thanks for pointing me to that. Seems like it should have gone to stable
Alright. Here is what I do now:
boot with intel gpu, amdgpu is blacklisted in modules so it doesn't get autoloaded
then i load amdgpu with dc on or off by hand, this time i make sure display that is attached via DisplayPort to amdgpu is on
i cannot unload until i use
echo 0 > /sys/devices/virtual/vtconsole/vtcon1/bind
here is with dc=1:

Encountering a deadlock in DRM while trying to force disable CRTCs. If no displays connected - system hard hangs. If DC is disabled (any number of displays) - system hard hangs. Currently investigating the deadlock issue. Thanks Can you try with the latest amd-staging-drm-next from https://cgit.freedesktop.org/~agd5f/linux/log/?h=amd-staging-drm-next We just fixed a bunch of driver unload issues. It should be fixed now. Harry I have tried the latest staging next 2 days ago. Suggest you see there is a long standing issue with powerplay and buggy AMI bioses that don't properly set up MMIO BAR regiions that need to be worked around by your driver becuase the vendor says a 2 year old motherboard is too old to support firmware updates, even if Intel ME is a massive security risk in support emails. I'm actually thinking you guys need to add linuxbios/coreboot support for your driver if available the way things are going: https://forum-en.msi.com/index.php?topic=298468.0 I think Polaris 11 with buggy bioses that dont' properly setup PCIE MMIO BAR ranges have hell with the amdgpu driver and powerplay (no fan control) cooked cards etc. With your new powerplay code it gets even worse maybe and just doesn't boot in this condition. I work OK on 4.14.20 but with exactly the same config and amdgpu-staging-next from last updated 4 days ago I get this mess. Feb 23 01:41:59 hojuruku kernel: [drm] amdgpu kernel modesetting enabled.

If not, please open a separate ticket so as not to confuse two issues. I commented because the user here had the error relating to powerplay failing that I have seen in other threads. https://forum-en.msi.com/index.php?topic=298468.0 [46667.236028] kernel: amdgpu: [powerplay] failed to send message 309 ret is 254 [46667.236041] kernel: amdgpu: [powerplay] failed to send pre message 14e ret is 254 Thought this issue might be related to the motherboard bios not properly setting up MMIO BARs. I'll open a seperate ticket i a week if the Polaris 11 support is still broken after your next push to linux 4.16. I'm sure you at AMD would be aware of it. Using Polairs 11 I get the same error message btw when loading the latest (today) amd-drm-staging-next. I'll include debugging symbols and try again.

Hi Luke, it actually looks like you're running with DC disabled. Can you also try with amdgpu.dc=1 explicitly set? Potentially there are issues in multiple IP blocks, though we fixed a driver unload issue recently with DC enabled. Thanks I fixed this. I was going to open another ticket. Just mentioned it before. Still dc=1 isn't yet usable due to this: https://bugs.freedesktop.org/show_bug.cgi?id=103953#c7 I found out that the breakage was occurring due to kernel configuration options. I can provide a working and broken kconfig, but my money is on it wanting the amd iommu gart support even though the hardware isn't installed. This is loaded on demand by the amdgpu module. Disabling agpart didn't do much harm though. Would that affect performance if intel_iommu is enabled?

Ask me for the .config's for the kernel if you need them to replicate the defect if you need them. That's what triggered the error in my last comment I think though in that kernel I had ORC off and no symbols. You might want to review / tweak your Kconfig depends clauses. Thanks. Just to clarify, you aren't able to enable DC with your current Kconfig configuration, which prevents you from retrying on this ticket? If so, please just open a new bug rather than conflate the issue here. Once you're unblocked from testing DC with your configuration, we can look at this issue again. Cheers Still seen with 4.15.15 and dc=1. Not sure if this always reproduces or not, havn't tested this in a while.

I just looked at the comments again and based on Comment 2 this seems like expected behavior for now. So my update was kind of pointless.
