After an error occurred a system becomes gradually unresponsive to mouse and keyboard input. The problem is solved in the next version 6.6.31. See https://lore.kernel.org/linux-cve-announce/2024053033-CVE-2024-36887-6a66@gregkh/ A patch with links to reports on this error and some comments https://patchwork.ozlabs.org/project/intel-wired-lan/patch/20240417190320.3159360-1-vitaly.lifshits@intel.com/
This patch is in kernels >= 6.6.31
Shouldn't stable keyword be removed from 6.6.30 and added to some of next versions? If it shouldn't, it would be nice to add the patch to 6.6.30. I've applied it locally and it works for me.
