Description of problem:
ps/2 mouse is compiled into the kernel and if not plugged in before booting
linux would not work.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. plug off ps/2 mouse
2. reboot the system
3. try to run kudzu - it'll remove ps/2 from configuration
Actual Results: no mouse support
Expected Results: mouse should be detected and picked up
ps/2 mouse should be compiled as a module to fix this
traditionally, ps/2 is not a hotplug-capable bug. Current machines are probably
safe, but you can toast older machines electrically doing ps/2 hotplug.
well, keeping driver in the kernel will not help saving old machines from being
toasted with ps/2 on the fly connection but will definitely restrict users with
recent hardware to plug it in when they want or can
this also hasn't much to do with in-kernel vs module btw
I've occasionally plugged in keyboards and mice after boot, and that just works.
Yes kudzu gets confused but the kernel side just works.
Closing out bugs on older, no longer supported releases. Apologies for any lack
of response. Please attempt to confirm with more recent releases.
