Further datapoint: This only appears to happen if you try reboot from 
a netbooted kernel (userspace on local disk). Reboot from a fully 
disk-hosted netbsd works fine.

Odd.

As added google fodder, the full list of O2 IP32 R10k/R12k issues is:

- soft reboots cause the rebooted kernel to hang, seems to be
   specific to netbooted kernels in some way
- only the first 256MB of RAM is recognised
- Pretty unstable, prone to resetting, sometimes leaving:

   'crime: cpu error 4 at address .....'

   errors in the log. (r10k/r12k cache coherence, or incoherence
   rather, issue according to archives.).
