Extremely slow boot - encryption problems?

I'm running LUKS (no LVM) on a large encrypted root and an encrypted swap.  During boot (using systemd), two long (about 1.5 minutes) happen.  Right after I'm prompted for a password for root (from encrypt hook) and while trying to load the encrypted swap, it times out waiting for swap.

journalctl -b is littered with messages like

Dec 25 09:51:38 localhost kernel: sd 4:0:0:0: [sdb] Unhandled sense code
Dec 25 09:51:38 localhost kernel: sd 4:0:0:0: [sdb]

Dec 25 09:51:38 localhost kernel: Buffer I/O error on device sdb, logical block 0

I fear it's a dying harddrive.  Any suggestions, please?

Re: Extremely slow boot - encryption problems?

Hum, well my first step to debug this would be to #comment out the lines in /etc/fstab for the SWAP and see if you still have the same problem.

If you do then you know the problem is somehow related to the Swap setup.
If you don't then you know it is probably not a problem with Swap.
