When I boot the laptop from shutdown state (not resuming or awakening), it quickly goes to the login screen as normal but the mouse and keyboard seem unresponsive, but not completely:
Every like 5-7 seconds I'm able to enter a keystroke or move the mouse. Using those time windows I'm able to enter the password and successful login.
Once I login, the laptop works perfectly fine and stable.
This is the log I recorded today when it happened again: http://pastebin.com/zaDp9xg9
It happens every time I fully reboot or shutdown the laptop, don't have any problems with suspension and awakening.
If I reboot resetting the PRAM, the problem doesn't appear until the next shutdown reboot. So what I usually do is reset the PRAM every time I boot.
I reinstalled the OS from scratch and the issue is still there. I also use FileVault.
Have anybody experienced a similar issue? Do you see anything strange in the log?
