I had between 4 and 10 spontaneous reboots after upgrading from 1.2E-DMA
(the bounce buffer test kernel) to 1.2G.  Every one of them was a dup
alloc error.  The last one was 1 day, 11:31 hours ago.  I didn't see any
pattern to it.  One thing I did notice was that the disk got REALLY busy
(like maybe writing a dump file to swap or locked in some disk-bound
deadly embrace??) for about 15 seconds, and then rebooted.

fsck finally fixed it, I think.

I upgraded to 1.2G programs when I did the last upgrade, so most of my
user-land stuff was still old (1.2C or D, maybe)
