I've occasionally seen this sort of message in early boot then the system continued to work perfectly so I figured it was an early-boot glitch. I suggest asking someone who understands RCU. > > The entire log is here: > http://download.netcenter.hu/bughunt/20090518/messages > > The system is on the md1, and working, but slowly. How slowly?

It usually points to some sort of hardware problem, but it is very hard to trace. Is the power supply rated high enough to support all devices? I cannot think of anything else to suggest .. except start swapping components until the problem goes away...
