Latest available kernel for Ubuntu 24.04.3 LTS, 6.14.0-32-generic (x86_64), is failing to install as a result of the following driver issues:

Would it be possible to get a fix for this?

As a temporary solution, I ended up holding the kernel version:

sudo apt-mark hold \
  linux-image-6.14.0-29-generic \
  linux-headers-6.14.0-29-generic \
  linux-modules-6.14.0-29-generic \
  linux-modules-extra-6.14.0-29-generic \
  linux-image-generic \
  linux-headers-generic \
  linux-generic

And purging all linux* packages that had a version different from 6.14.0-29

This is OK temporarily, but I would really appreciate an mlnx-en version which is compatible with the latest Ubuntu 24.04 LTS.

If anyone has a better alternative, please share.

Hi there @gerhardlazu, welcome to the NVIDIA developer forums.

Since this is a Mellanox specific issue, I move your post to a more related category, I hope that is ok.

Thanks!
