This started with 5.5 and hasn't gotten better since then, despite some reports I tried to send. As per my previous message: I have a Thinkpad P70 with hybrid graphics. 01:00.0 VGA compatible controller: NVIDIA Corporation GM107GLM [Quadro M600M] (rev a2) that one works fine, I can use i915 for the main screen, and nouveau to display on the external ports (external ports are only wired to nvidia chip, so it's impossible to use them without turning the nvidia chip on). I now got a newer P73 also with the same hybrid graphics (setup as such in the bios). It runs fine with i915, and I don't need to use external display with nouveau for now (it almost works, but I only see the mouse cursor on the external screen, no window or anything else can get displayed, very weird). 01:00.0 VGA compatible controller: NVIDIA Corporation TU104GLM [Quadro RTX 4000 Mobile / Max-Q] (rev a1) after boot, when it gets the right trigger (not sure which ones), it loops on this evern 2 seconds, mostly forever. I'm not sure if it's nouveau's fault or the kernel's PCI PME's fault, or something else. Boot hangs look like this: [ 10.659209] Console: switching to colour frame buffer device 240x67 [ 10.732353] i915 0000:00:02.0: [drm] fb0: i915drmfb frame buffer device [ 12.101203] nvidia-gpu
