It seems that removing/loading/removing scsi_wait_scan module takes
some time on your system. This could be a kernel or hardware specific
problem.

How about dmesg?

Thanks for the help! It appears scsi_wait_scan isn't even getting loaded as lsmod doesn't show it. I moved the file /lib/systemd/system/fedora-wait-storage.service out of the way, for some reason you can't disable that particular service. Anyhow the delay is gone, woohoo!

I searched all the log files including dmesg, didn't see anything but I could have easily missed it. I also grep'ed for scsi_wait_scan in all with no results. Once booted that module loads instantly, I'll test more later now that I know what is causing it!

Many thanks
