Public bug reported:

Hi,

My system is working fine with 5.13.0-40-generic kernel and nvidia-
driver-510...

Switching to 5.13.0-41 is messing something up...

Black screen after grub.

No graphic at all (black screen).

Further investigation show problems with the nvidia module :


----------------------------------
nvidia 0000:01:00.0: vgaarb: changed VGA decodes: 
olddecodes=none,decodes=none:owns=none
NVRM: The NVIDIA GPU 0000:01:00.0
NVRM: (PCI ID: 10de:1cb3) 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.
nvidia-nvlink: Unregistered the Nvlink Core, major device number 507
----------------------------------

modules nvidia-* are present and installed :

----------------------------------
dkms status
nvidia, 510.73.05, 5.13.0-40-generic, x86_64: installed
nvidia, 510.73.05, 5.13.0-41-generic, x86_64: installed
----------------------------------

but they can't be modprobed :

-----------------------------------
modprobe: ERROR: could not insert 'nvidia': No such device
-----------------------------------

Reboot on the 5.13.0-40-generic solve the problem.

We are numerous users here to have the same behaviour...
