Package: upgrade-reports
Severity: important
I was able to boot by selecting an older kernel - I then was able to run:
# systemctl mask systemd-udev-settle
and 3.16.0-4-amd64 now boots.
This apparently is related to Intel + ssd (drive details below)
I found bread crumbs here - https://bbs.archlinux.org/viewtopic.php?id=189106
But in this case it just hung for over 10min. I would be glad to provide more
information if needed and test fixes. Please be specific.

Hi Karl,
Thanks for taking the time to report an upgrade report.
I can see that the archlinux report (link found in the forum posts)
suggests this is a problem between ACPI and systemd/udev. If you have
acpid instaled, have you tried to uninstall acpid and unmask
systemd-udev-settle?
Note we have a issue between acpid and logind noted in our release notes[1].
OK - I did the following
# systemctl unask systemd-udev-settle
# dpkg --purge acpid
This lets it boot - but there is now a long delay as seen here from
the top of # systemd-analyze blame
18.124s systemd-udev-settle.service
11.393s nut-driver.service
4.151s systemd-fsck@dev-md6.service
3.508s accounts-daemon.service
<snip>
verses with systemd-udev-settle masked
16.651s nut-driver.service
351ms dphys-swapfile.service
(the nut-driver should not be so slow either ..)
My searches on systemd-udev-settle masked tell me it is about "fake block device storage technology"
(in my case mdadm - the raid)
I don't really need acpid on this system - it would be nice if it booted faster like it did.
Something is still broken - I suspect it has to do with the boot from a pair of raid-1 solid state
drives (acpid gets confused by trying to monitor the fake block device?) .
Hope this has been helpful anyway.
