It turns out that disabling ntpd let the system run for a longer period 
of time - until I ran "sysctl sys" at which point I got a panic.

And this time the panic actually implicates amdgpu.ko, which is an 
improvement:


#9  0x0000000000000000 in ?? ()
#10 0xffffffff82a14c4e in amdgpu_device_get_pcie_replay_count ()
    from /boot/modules/amdgpu.ko
#11 0xffffffff82a14b80 in sysctl_handle_attr () from /boot/modules/amdgpu.ko

#12 0xffffffff80c06cc1 in sysctl_root_handler_locked 
(oid=0xfffffe02133ff000,
     arg1=0xfffffe016e360980, arg2=-8724518803888, req=0xfffffe016e360980,

#13 0xffffffff80c0610c in sysctl_root (oidp=<optimized out>,

Since it _is_ a problem in amdgpu, I'll stop this thread and re-post on 
freebsd-x11.
