I've spent weeks trying to diagnose this so I'm pleased it's not just me! The "solution" is the same as Henrich reports. Booting with kern.smp.disabl= ed=3D1 is successful and I'm able to login graphically. If I build 14-STABLE with some debugging options enabled, it will boot with= SMP enabled maybe 2 out of 3 times, and otherwise it locks up during boot (usua= lly just after bringing the network interfaces up). Once it boots (with or with= out SMP), everything seems stable, suspend/resume works and I can do intensive tasks like buildkernel. But of course things are slower due to the debugging options. Happy to try things out, unfortunately the T400 is not getting any younger = and make buildkernel without SMP takes well over 1 hour, so things take a bit of time to test!
