Despite the first boot working successfully, I rebooted it again this morning, after it had been running for quite a few hours, and the panic occurred 6 times before the system came up to multiuser successfully. The backtrace is always the same, and looks like: spin lock 0xc0c62030 (smp rendezvous) held by 0xfffff8000552fb60 (tid = 100351) too long timeout stopping cpus panic: spin lock held too long cpuid =3D 1 KDB: stack backtrace: #0 0xc051fef0 at _mtx_lock_spin_failed+0x50 #1 0xc051ffb8 at _mtx_lock_spin_cookie+0xb8 #2 0xc0887a1c at tick_get_timecount_mp+0xdc #3 0xc05420fc at binuptime+0x3c #4 0xc08516cc at timercb+0x6c #5 0xc0887d80 at tick_intr+0x220 Uptime: 23s Again, I=92d love any thoughts.
