------- Comment #35 from [EMAIL PROTECTED] 2008-03-13 11:02 -------
Without CONFIG_HZ, it's even worse. The computer is directly blocked when X
started and a few seconds after, the screen becomes black. It's also impossible
to connect via SSH to the computer.
With CONFIG_HZ enabled and hpet=force as boot parameter, it hangs also when X
is started, but not completely. I can make an SSH connection. The output of cat
/proc/interrupts is the following:
