I can report the same issue with 14.2-RELEASE, and also 14-STABLE on a T400.
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.disabled=1
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 (usually
just after bringing the network interfaces up). Once it boots (with or without
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!
Regards,
Anthony
