Boot the broken kernel; wait for hang ... boot the working kernel do
journalctl -b -1 -e and you should see the log of the failed boot.
Unfortunately, it seems that "journalctl -b 1 -e" is showing the wrong boot log
:(

I rebooted to the bad kernels some moments ago, so it should be Apr 04 21:20 (CET).
By the way, I did a full journal dump to a text file and found a smoking gun...
NetworkManager!

I have rebooted to the bad kernels with WiFi adapter removed and they boot okay! Of
course, as soon as I plug my WiFi adapter back - rt2800- or reconfigure my wireless
connection to use the non-used ipw2200... my laptop locks hard.
So, where would the bug report belong? NetworkManager or Kernel?
