Thank you amd, now I can't use Linux

[gradinaruvasile]

So. Tried

ignore_loglevel drm.debug=14 log_buf_len=16M

And logged via netconsole until it froze. Because i use a bridge on the desktop, i had to enable logging run time so the beginning of the boot isnt visible...

Im not convinced it is really helpful, but may be for developers. It is full of radeon debug output, mainly display initialization (which occurs far more times than the display was switched off by dpms). I have a monitor connected to CRT1 (analog cable).


Here is a dmesg, which shows the first part of the boot for reference, pasted from this current session (which was alive and well at that point):

PS i tried drm.debug=15 and drm.debug=1 (which seems to be the same), but i got dozens of lines per second and a kern.log of 547MB after i had to reboot due to intense swapping.
