Numlock light gets off after hibernation

Hardware Environment: Celeron; PS/2 keyboard
Software Environment: hibernate script
Before hibernating NumLock is on.
After resume numlock light on the keyboard is off. (But keyboard acts as if it
would be on.)
Workaround: press NumLock key twice.
Steps to reproduce:
1. Turn numlock on.
Does it work properly if you start hibernation while in text console as ooopsed to being in X?
I can reproduce it on similar hardware.
If hibernation is started from a text (FB, to be precise) console, the keyboard works properly (ie. the numlock status is restored).
So, are we going to do anything about it?
I need to finish moving LED handling into generic resume in input core. That will ensure that all keyboards work the same way. However X manages LED state outside of kernel and so we can't really do anything...
And X is very stupid - it does not properly restore LED state if you hit CapsLock and switch to a text console and back. I know that the kernel is working because LED state is restored properly if you switch between text VTs.
So, this is not a kernel bug, but an X problem.
I think we should close this entry, then.
I think the numlock restore still does not work for USB keyboards so closing it is premature.
OK, sorry. Should I reopen?
