I am surprised by your success with r262743. I just got 04e37d68 to crash on me; that corresponds to the much earlier r262349. It booted fine at least twice but then crashed in the usual place. The backtrace is a little different this time and seems not to include any noise from bge, but it's still right around the time when networking is coming up: Setting hostname: hydra.priv.oc.ietfng.org. tap0: Ethernet address: 00:bd:00:00:57:00 tap1: Ethernet address: 00:bd:00:00:58:01 spin lock 0xc0c5f420 (smp rendezvous) held by 0xfffff80005f90920 (tid 100328) too long timeout stopping cpus panic: spin lock held too long cpuid =3D 1 KDB: stack backtrace: #0 0xc05204b0 at _mtx_lock_spin_failed+0x50 #1 0xc0520578 at _mtx_lock_spin_cookie+0xb8 #2 0xc088849c at tick_get_timecount_mp+0xdc #3 0xc054275c at binuptime+0x3c #4 0xc08521ec at timercb+0x6c #5 0xc0888800 at tick_intr+0x220 Uptime: 23s I'm currently going way back to 44aad33d (r261716) and will see what happens.
