if the X kbd driver selection is tweaked to a simpler model, say:

Or perhaps just test with CFS reverted? It really sounds more like something
independent from the scheduler. Perhaps someone could put a CFS-revert-for-testing patch
on ftp somewhere. It's only a few git changesets so shouldn't be too difficult to
do.

Teresa was already using 2.6.22.1, with CFS (v19.1) patched in, so reverting
that would be a matter of patching it out again. She said she wasn't seeing
trouble on other kernels though.

I was the one who also saw keyboard trouble on 2.6.22.1 without CFS by the
way -- and haven't (yet) seen any anymore since patching _in_ CFS v19.1...

Could the people who had or have keyboard problems try out Dmitry's
input locking patches, and see if those help: http://lkml.org/lkml/2007/7/24/17
And if it does, report it to him, either there or here after CCing him.
