The troubleshooting kernel command line option nomodeset unfortunately changes the way framebuffer interactions work with graphics devices which in some cases can result in kernel memory to be used for graphics updates. When this happens on some specific hardware common in rack mount servers with baseboard management controllers, this can cause the memory bus to become locked for a brief time while the graphics update is occuring. This locked memory bus means disk IO can become blocked, and network cards can overflow their buffers resulting in packet loss on top of the latency incurred by the graphics update executing. As such, we've removed the nomodeset option from default usage and added a note describing its removal to the documentation along with a release note.
