I updated my HP ProBook 4525s with OEM preload SLED11 to SLED12. Looks
fine, but one issue - mouse and keyboard randomly not responding. I can
work 5 minutes or 1 hours but suddenly I lose control of OS. At the same
time, the computer does not hang, the clock is running, pictures moving,
sound is played. I can connect to SSH server and doing anything. After
some time mouse and keyboard come back responding and I can work again.
This time may be 2 minutes or 30 minutes - also randomly. I found two
regularities of come back responding (but not lose control): control
returns always if I connect to display:0 by VNC or if the screen light
out by energy saver. In /var/log/messages I has no find any correlations
of lose control...
Any suggestions?
