Public bug reported:
When booting with kernel 6.17.0-19-generic on a system with NVIDIA GPU
(driver 570.211.01) and Intel NVMe SSD, a kernel panic occurs with the
following message:
```
VFS: Unable to mount root fs on unknown-block(0,0)
```
Booting with the previous kernel (6.14.0-37-generic) succeeds without any issue.
## Root Cause:
The hook script `/usr/share/initramfs-tools/hooks/framebuffer-nvidia` provided
by `nvidia-kernel-common-570` contains the following line:
```
shcopy_modules_dir_filter updates/dkms nvidia
```
This unconditionally copies all NVIDIA DKMS modules (nvidia.ko, nvidia-drm.ko,
nvidia-modeset.ko, nvidia-uvm.ko, nvidia-peermem.ko) into the initramfs as
uncompressed .ko files, regardless of whether they are needed at early boot.
The resulting initramfs was abnormally large (223MB vs ~80MB for other
kernels). This appears to cause a failure during early boot with kernel
6.17.0-19-generic, preventing the root filesystem from being mounted.
The same hook exists when using kernel 6.14.0-37-generic, but no kernel panic
occurs with that kernel.
## Workaround:
```
sudo chmod -x /usr/share/initramfs-tools/hooks/framebuffer-nvidia
sudo update-initramfs -u -k 6.17.0-19-generic
```
Environment:
Output from `lsb_release -rd`:
