I find quite hard to believe this was caused by recent syscons
changes.  Because these changes are about /dev/random thingie and
color attribute handling in terminal emulator part of syscons. They
have nothing to do with keyboard and mouse input.

I am suspecting there may be something in tty interrupt handling in
general in the kernel...
