Does reverting: commit 33b3ad3788aba846fc8b9a065fe2685a0b64f713 Author: Christoph Hellwig <hch@lst.de> Date: Thu Aug 15 09:27:00 2019 +0200 drm/radeon: handle PCIe root ports with addressing limitations radeon uses a need_dma32 flag to indicate to the drm core that some allocations need to be done using GFP_DMA32, but it only checks the device addressing capabilities to make that decision. Unfortunately PCIe root ports that have limited addressing exist as well. Use the dma_addressing_limited instead to also take those into account.

Does this revert fix the issue?
Does it work correctly with 5.9-rc1 or newer? Another thing to try, does setting radeon.agpmode=-1 fix the issue?

(In reply to Alex Deucher from comment #6) > Another thing to try, does setting radeon.agpmode=-1 fix the issue? I add it to grub but the issue still exists. same problem. (i guess with "noisy" you mean "unreadable") i face the problem with mint and manjaro installer kali installation worked but the problem occurred after the first reboot i forgot to mention that i have "AMD RV620/M82 [Mobility Radeon HD 3450/3470]" i tried same live usb with persistence on other pc (buitin intel somewhat) and all worked fine |
