Yes, disk i/o seems likely, although shouldn't be hugely worse than any
of the other systems...  Waiting on native sata hardware to become
available... so it's currently using a usb-sata adapter. Hopefully that
will resolve the issue.

Hrm. that's a new one! Didn't see it myself during the bring-up
testing:

odc2a login: [ 8759.086506] haveged[8523]: unhandled level 3 translation
fault (11) at 0xabf1147c, esr 0x92000007
...
[ 8779.711346] haveged[8703]: unhandled level 2 translation fault (11)
at 0x93c6374c, esr 0x92000006

Will experiment with combinations of stretch, kernel versions, etc. and
see if it behaves the same.

Ah well... will do more troubleshooting and make those nubmers
better. :)
