T1200 GPU not initialized and failed with "NVRM: fallen off the bus and is not responding to commands."


everytime I tried to activate my nvidia card I got the following error message

NVRM: The NVIDIA GPU 0000:01:00.0
NVRM: (PCI ID: 10de:1fbc) installed in this system has
NVRM: fallen off the bus and is not responding to commands.
nvidia: probe of 0000:01:00.0 failed with error -1
NVRM: The NVIDIA probe routine failed for 1 device(s).
NVRM: None of the NVIDIA devices were initialized.

I already tried typical hints which can be fount if you search in google like

rcutree.gp_init_delay=1 rcutree.rcu_idle_gp_delay=1 pcie_aspm=off

non off these works.

I’m using the latest nvidia driver (470.63) on opensuse leap 15.3

nvidia-bug-report.log.gz (1014.1 KB)

after I blacklisted bbswitch completely, the driver loads properly.

looks like bbswitch is not able to activate/deactivate the graphic card correctly.

will try more, to find out why.
