Comparing to a dmesg output of a successful boot I fail to see much difference.
All in all I found 4 lines that appear to be missing in the screenshot:
[ 0.499001] Monitor-Mwait will be used to enter C-1 state
[ 0.499021] Monitor-Mwait will be used to enter C-2 state
[ 0.499041] Monitor-Mwait will be used to enter C-3 state
...

Screenshot when system is frozen added.
