Sorry... my "bug" was PEBCAK! It has nothing to do with entropy. I copied the system from an old HDD to a SDD, and in the process didn't change the resume UID that sits in: /etc/initramfs-tools/conf.d/resume
It was still pointing to a partition UID on the old disk. Hence when the old disk was attached via USB all was normal, but when the disk was not there, the system waited for 30 seconds to see that UID and try to resume. I then replace the old UID with "none" (since I won't be hibernating that machine) did the initram command, and now all is fine. So please, disregard posts #66 to #69, they are unrelated to the topic!
