Comment 0 for bug 1957753

There is an issue with hypervisor host side mlx5 driver operation on Bluefield devices in kernels <=5.16 that was recently fixed in master with a one-liner:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=7846665d3504812acaebf920d1141851379a7f37

It would be good to have this fix in Focal+ kernels.

This is not needed in https://bugs.launchpad.net/ubuntu/+source/linux-bluefield since it's used at the DPU side whereas the issue in question affects the hypervisor side.
