Thanks YS1 for your check.
There is no clear error in the messages, so it is down trying to log what
activity goes on while it is waking up.
Chances are that the things we set up are too sluggish as well and only start
to report after we unfrozen far enough, yet it is worth a try.
You could run things like
$ sar -A -I XALL 1 > freezeslow.sar
$ dstat -tvins --top-io-adv --top-bio-adv --top-latency 1 > freezeslow.dstat
$ iostat -xtdk 1 > freezeslow.iostat
Then suspend restore and the processes should wake up and log again.
With some luck (before going much deeper on debugging suspend) we can catch
something that makes things worse in your case.
