The GPU did hang a few times and the kernel was able to recover. But later the kernel was caught in an infinite loop of GPU hangs and I was not able to take back the control of the X server and therefore I lost unsaved work in my X session. Between 2 hangs I was able to switch to a VT and run dmesg, so here is the end of the kernel log: [73670.536108] radeon 0000:01:00.0: GPU lockup CP stall for more than 10168msec [73670.536200] radeon 0000:01:00.0: GPU lockup (waiting for 0x00000000000c7f78) [73670.536203] radeon 0000:01:00.0: failed to get a new IB (-35) [73670.536255] [drm:radeon_cs_ib_chunk] *ERROR* Failed to get ib !
