5.7-rc1 and rc2 regression from kernel 5.6.0
After starting X/plasma on 5.7-rc1 and rc2, system runs for a few seconds to a few hours, then display freezes. The pointer continues to be movable and audio will continue to play for some seconds but they eventually stop as well. The kernel remains alive at least enough to reboot with SRQ-b, not sure if previous SRQs have any effect or not.
Sometimes but not always there's a gpf left in the log, appearing to confirm it's amdgpu (the -dirty is simply a patch making mounts noatime by default):

That's it. Nothing in the log since boot before, and the next entry is after reboot.
