I am using a PS2 keyboard now but has the same effect though in a
reduced intensity.
There are no messages in /var/log/messages how ever when I use the PS2 keyboard.

Changing ports does not work :-(

I tried all these combinations and did not help :-(

blk-build# sysctl kern.emergency_intr_enable=1
kern.emergency_intr_enable: 0 -> 1
blk-build# sysctl kern.emergency_intr_freq=50
kern.emergency_intr_freq: 10 -> 50
blk-build# sysctl kern.emergency_intr_freq=100
kern.emergency_intr_freq: 50 -> 100
blk-build# sysctl kern.emergency_intr_freq=1000
kern.emergency_intr_freq: 100 -> 1000
blk-build# sysctl kern.emergency_intr_freq=5
kern.emergency_intr_freq: 1000 -> 5

Also I note that this problem exists only when I start Xorg before
that the system is just fine.
But once Xorg is started using  'startx' this problem surfaces and
persists in the console too even afterwards it is killed.
Only reboot solves the problem.
