Note that after the kernel is selected in the grub menu, it flicks to a white cursor on a black background. I can't hit ctrl+alt+del nor can I switch to any tty terminal. this is what i mean by 'the only option is to hit the power button'. still an issue with 5.11.5-50.fc33 tried the options provided by the kernel team to the user in the referenced kernel bugzilla bug, nomodeset and amdgpu.dc=[0|1] makes no difference to the boot status I second this, faced the same problem with both 5.11 and 5.12 (rc) kernels as well. This is clearly a regression since latest 5.10 releases (5.10.20, 5.10.21 & 5.10.22) with 5.9 and 5.8 releases worked totally fine. I also have Stoney chip in my configuration: https://linux-hardware.org/?probe=f40d786ac2 As per the attached Kernel bug, further testing on my part shows this is an issue all the way back to 5.11-rc1. I am troubleshooting with the Kernel team to try and find the commit that introduced the issue. After further testing with the Kernel team, I can now boot 5.12-rc3 with the iommu-fixes branch of the git tree mentioned here: https://bugzilla.kernel.org/show_bug.cgi?id=212133#c23. I imagine this will be made available in an upcoming kernel release and pushed to 5.11 as well. These are specifically AMD IOMMU fixes. I have discovered I can properly boot 5.11 series kernels with iommu=soft as per https://www.kernel.org/doc/Documentation/x86/x86_64/boot-options.txt, This means that until the fix provided by Joerg Roedel is upstreamed, we at least have a workaround. This is still an issue with 5.11.7-200 on Fedora 33 Same here on a Lenovo Ideacentre 310S-08ASR (AMD A9-9425 CPU) running the 5.11.7-200.fc33.x86_64 kernel. Adding iommu=soft works around the problem. Looks like the fixes are now available in 5.12-rc4, but not 5.11 yet *** Bug 1941232 has been marked as a duplicate of this bug. *** 5.11.9-200.fc33 fixes this issue (currently in Koji, soon to be in updates testing) 5.11.9-200.fc33 has resolved the problem for me. Same as comment #13 ^^ - latest kernel 5.11.9-200 (f33 x86) has resolved the problem. Essentially likewise to the two above comments: I didn't get around to updating until 5.11.10-200.fc33.x86_64 had shown up, but with it the problem has been resolved (no more need for the iommu=soft workaround). Closing this, since multiple people have confirmed that this is fixed in 5.11.9 / 5.11.10 and newer. Interesting, I still have this happening on F34 with kernel 5.11.11, although it looks like a race as occasionally it works. 5.11.10 works consistently well. 5.11.12-300 kernel F34 here, any higher version causes errors above and unfortunately, even the workaround does not work.
