[19:34] <enyc> Hrrm... On Thinkpad E520 (2nd gen core) system, we are noticing in current  Ubuntu LTS Kernel 5.4 --  Hotplug of the eSATA hard disk isn't working, but I'm fairly sure it did work, on older systems (maybe pre-k 5.4)
[19:34] <enyc> reboot and disk appears, etc...
[19:34] <enyc> indeed it can be connected by USB2.0 but anyhow!
[19:35] <enyc> I wondering if this sort of thing not surprising.
[19:35] <enyc> I've similarly noticed some with  core-2-duo systems (e.g. Inspiron 6400)  can no longer detected External VGA monitor resolution, which used to work.
[19:35] <enyc> I guess older hardware less-tested rarer etc
