https://bugs.freedesktop.org/show_bug.cgi?id=104598 --- Comment #4 from Christoph Haag --- Yes it also happens with modesetting. It is a bit different though as the messages switch to Device or resource busy very quickly [ 26.386] (WW) modeset(0): flip queue failed: Cannot allocate memory [ 26.386] (WW) modeset(0): Page flip failed: Cannot allocate memory [ 26.386] (EE) modeset(0): present flip failed [ 26.387] (WW) modeset(0): flip queue failed: Cannot allocate memory [ 26.387] (WW) modeset(0): Page flip failed: Cannot allocate memory [ 26.387] (EE) modeset(0): failed to set mode: Invalid argument [ 26.404] (WW) modeset(0): flip queue failed: Device or resource busy [ 26.404] (WW) modeset(0): Page flip failed: Device or resource busy [ 26.404] (EE) modeset(0): present flip failed [ 26.422] (WW) modeset(0): flip queue failed: Device or resource busy [ 26.422] (WW) modeset(0): Page flip failed: Device or resource busy also modesetting doesn't recover once vkmark quits, the messages keep spamming and X keeps being screwed up (feels laggy and some synchronization artifacts). Disabling kwin compositing then makes X freeze completely. But that may be unrelated since modesetting seems to have other issues too, like freezing on a black screen when exiting X or tty switching. It could indeed be an issue with kwin/radeonsi that just happens to be triggered by two different vulkan drivers with this one specific application in mailbox present mode. -- You are receiving this mail because: You are the assignee for the bug.
