I am almost sure that you are correct. But to me it was a symptom showing that the system was indeed very slow with either of the SSDs installed, but not necessarily due to those drives. That combined with the slowness starting in or immediately after the grub-stage pointed me in the direction of a hardware-related issue. Reseating all removable hardware and connectors seems to have resolved most of the slowness (not all though). Meanwhile I have ordered a new laptop to replace my old Thinkpad W530 of 2012. In a few days I will be the proud owner of a maxed out Thinkpad P1. I am sure I will notice the increase in speed and especially the 32GB RAM when having multiple VMs open at a time. Can wait! Keeping my fingers crossed hoping the BIOS problems have been solved and it will be easy sailing installing current testing on it. Anyone have any experiences with this laptop to share? I'd appreciate to hear about it. P.S. This will be my fourth Thinkpad. All have been serving me for years before being replaced. This was the first that has ever given me any trouble. As a matter of fact all of them do still work. I do like those darn machines! Grx HdV
