--- Comment #33 from Jerome C (me@jeromec.com) --- (In reply to kolAflash from comment #32)
In the meanwhile I performed test number 2.
- amd-drm-next-5.14-2021-05-12* without ip_block_mask=0x0ff, with Xorg
[...]
This time the crash was very different!
After some minutes (about 3) the graphical screen actually turned back on. I'm pretty sure that didn't happen with the other kernels I tested. (never tested amd-drm-next-5.14-2021-05-12 before)
Nevertheless everything graphical is lagging extremely. If I move the mouse or do anything else it takes more than 10 seconds until something happens on the screen.
On the other hand SSH access is smoothly possible. And I was able to save the dmesg output. (see attachment) Unlocking the screen via SSH (loginctl) or starting graphical programs (DISPLAY=:0 xterm) works, but is extremely slow too. (> 10 seconds waiting)
I experienced this laggy too although I didn't try the SSH thing ( I don't have it setup )
