Looking your dmesg:
Sep 30 17:24:27 kernel: nouveau 0000:01:00.0: DRM: DCB version 4.1
Sep 30 17:24:27 kernel: nouveau 0000:01:00.0: DRM: MM: using COPY for buffer copies
Sep 30 17:24:27 kernel: [drm] Initialized nouveau 1.3.1 20120801 for 0000:01:00.0 on minor 1
I would assume it runtime suspends here. Then it wakes up because of PCI
access from userspace:
Sep 30 17:24:42 kernel: pci_raw_set_power_state: 56 callbacks suppressed
and for some reason it does not get resumed properly. There are also few
warnings from ACPI that might be relevant:
Sep 30 17:24:27 kernel: ACPI Warning: \_SB.PCI0.GFX0._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20190509/nsarguments-59)
Sep 30 17:24:27 kernel: ACPI Warning: \_SB.PCI0.PEG0.PEGP._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20190509/nsarguments-59)
This seems to be Dell XPS 9560 which I think has been around some time
already so I wonder why we only see issues now. Has it ever worked for
you or maybe there is a regression that causes it to happen now?
