https://bugzilla.kernel.org/show_bug.cgi?id=85421 --- Comment #37 from EmanueL Czirai <emanueLczirai@xxxxxxxxxxxxx> --- Created attachment 172011 --> https://bugzilla.kernel.org/attachment.cgi?id=172011&action=edit instant blanking without recovery when radeon.lockup_timeout=20 I accidentally added kernel param: radeon.lockup_timeout=20 which made it blank in firefox without being locked up or frozen first, and remained blank, but i was able to ctrl+alt+del of course. But this tells me that the (soft?)reset gpu thing isn't working. Is there a way to make it work? If that doesn't work normally, that explains why when it really locks up, it can't get back to life again unless a warm boot happens. If this would work, then I assume it would be able to recover from the current issue being described in this thread. the log for this case is attached (search for: 20msec ) the problem i guess are these: Mar 24 17:00:42 manji kernel: [drm:radeon_dp_link_train] *ERROR* displayport link status failed Mar 24 17:00:42 manji kernel: [drm:radeon_dp_link_train] *ERROR* clock recovery failed btw the correct param I wanted was: radeon.lockup_timeout=20000 for 20 sec. and by now I have also added some extra kernel params: nohz=on rcu_nocbs=1-3 pcie_aspm=force radeon.audio=0 radeon.lockup_timeout=20000 radeon.test=0 radeon.agpmode=-1 radeon.benchmark=0 radeon.tv=0 radeon.hard_reset=1 radeon.aspm=1 radeon.msi=1 radeon.pcie_gen2=-1 radeon.no_wb=1 radeon.dynclks=1 radeon.r4xx_atom=0 radeonfb radeon.fastfb=1 radeon.modeset=1 radeon.dpm=1 radeon.runpm=1 which still allow me to reproduce the issue described in the previous comment. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
