I've had this error consistently at every boot, right near the end of init scripts. CPU usage goes to full and the system locks up. Every time. This has happened with all of the 2.6.17 generic kernels. Going back to 2.6.15 fixes the problem. Going to 2.6.17-386 kernel also fixes the problem, but it's not an SMP kernel, which I need.
