ADDITIONAL INFORMATION
Encrypted root-on-ZFS (originally installed with Ubuntu 25.04).
The ZBook is currently docked, with one display on DisplayPort connected to the
HP dock.
Before I began experimenting with settings: a mobile hard disk drive was
connected to the dock. USB. This drive contains a ZFS pool that was imported
(lsof output below). Exporting the pool did not alter the effect of waiting
more than one minute for OS sleep to occur.
