OK, done that. The first reboot came up OK, sods law being what it is 
the next few boots will be clean and I'll have to wait a while for 
results from the next panic but in the meantime here's the messages 
generated by WITNESS for the clean boot:

curlew:/home/mike% grep WITNESS /var/run/dmesg.boot
WARNING: WITNESS option enabled, expect reduced performance.
WITNESS: spin lock scrlock not in order list
WITNESS: spin lock intrcnt not in order list
WITNESS: spin lock ctl.rm_mtx not in order list
WITNESS: spin lock dev.rm_mtx not in order list

... do they give any clues?
