I have been trying out fedora 40 beta on a Dell XPS 15 9500 with integrated Intel UHD graphics and discrete Nvidia graphics. Everything worked perfectly with the 6.8.1 kernel and using nouveau but things started to happen after the upgrade to kernel 6.8.2 and later 6.8.4 kernel. First thing was an extremely slow boot, more than 3 minutes: systemd-analyze blame 3min 18.876s sys-module-fuse.device 3min 18.817s dev-ttyS11.device etc, etc. Looking with journalctl -k -b shows a very long list of entries for nouveau regularly containing the lines: kernel: nouveau .&checktime(0000,01,00,':').0: disp: one-time init failed, -110 kernel: nouveau .&checktime(0000,01,00,':').0: DRM: [DRM/00000000:drmDevice] [NEW dispc570] (ret:-110) kernel: WARNING: CPU: 11 PID: 452 at drivers/gpu/drm/nouveau/nvkm/subdev/gsp/r535.c:112 r535_gsp_msgq_wait+0x1a9/0x1d0 [nouveau]es: ---- kernel: nouveau .&checktime(0000,01,00,':').0r -110: gsp: fini failed, -110 kernel: nouveau: probe of .&checktime(0000,01,00,':').0 failed with error -110 I have not investigated if nouveau is the cause of these problems but it in any case appears to be implicated and there are also power management problems. Normally this laptop has a battery rate between 9-11W but now shows a rate above 25W in small task use.
